Reddit mentions of California Air Tools CAT-1610A Ultra Quiet and Oil-Free 1.0 Hp 1.6-Gallon Aluminum Tank Air Compressor

it really depends on your budget. One of my favorite brushes is a badger 105 patriot found here

This brush will last you a long time with proper care. It's also reasonably priced and has a great spray pattern (pencil line to almost three inches). As for a compressor I personally use a California air tool - quite air model found here

I use this guy because of the large tank and because it has a rust free tank. Most model or little compressors have tanks that are made out of iron which will rust after some time. But depending on how much you wanna spend here are ones I would recommend because they come with a tank and an adjustable regulator/water trap (but as you can see they are not to far off from the California one)

I have the second one in that list, however after a year the tank rusted even with proper care :(

Why on that website? The stuff on there is both expensive and pretty crappy.

Gun to my head, I'd go for this one, but it's $25 cheaper for the same stuff on Amazon.

I'll break down why for you, too.

The Iwata Eclipse HP-CS is a damn fine airbrush. It's not gonna give you the finest lines or the broadest strokes in the whole wide world, but it will keep on kicking and you can depend on this thing for a long, long time. You can cheap out on the airbrush in a pinch, but you're looking for a bad time if you skimp on your tools. 3 crappy airbrushes can't compete with one rock-solid one.

If you're going for a compressor, get one with a tank for multiple reasons.

1. It's not constantly running. It builds up pressure in the tank and then shuts off the motor for silent running.
   
   
2. No surges. Running straight from the compressor will give you pulsations in your airflow, which could affect your paintjob. Putting that tank in there keeps everything smooth.
   
   
3. It's not constantly running. Why would you want your bargain-basement compressor running constantly? That's just begging for an early equipment failure.
   
   I'm not trying to be a dick about it. Airbrush-specific compressors fall into two categories: affordable garbage and expensive perfection. There doesn't seem to be a reasonable middle ground. I'd suggest you skip the "airbrush" tag altogether and get a standard air compressor from the hardware store (or online, whatever tickles you) and run with it. For $10 in fittings, you'll have whatever PSI you want where you want it and you're not paying that hobby tax. I use this compressor and it's pretty fantastic. Quiet compared to most compressors, cheaper than most, and it kicks on once every 5 minutes or so for about 20 seconds while I'm in the thick of things. It's not as silent as the $400-$1200 compressors for airbrushing, but it's quiet enough during full-tilt operation to hear the TV from the other room.

look at the warehouse deals, its about 140 or 150 depends on your state.

Here is a youtube video of a much larger model... https://www.youtube.com/watch?v=ZZryRKHrCKc

I have this one (as well as a Krome) and aside from being a bit louder than I would like, but it does a great job. If you have amazon prime, it is even better; you'll save a ton on shipping

A couple questions to consider:

• Are you in the US, EU, or Asia?
  
  
• How much do you want to spend?
  
  
• How comfortable are you with DIY and home improvement projects? How good are you with tools?
  
  
• How much do you want instant gratification vs having to debug, learn, and troubleshoot on your own?
  
  I assume you're in the US because you linked to Amazon US. And because you came to the conclusion that you should get an Iwata or Badger.
  
  Let me address the spray booth first. The main selling point and feature of the booths you linked on Amazon is portability. They're not that portable, but because they fold up they are more portable than something you might build out of a plastic storage bin and some fans. If you feel like you can build your own (there are lots of articles on the internet for this) that meets your (safety) requirements/desires for less than the portable spray booths online, than you might want to consider building your own. Otherwise, what you're paying for is the ability to fold it up and bring it on trips to group builds. Also keep in mind that these used to go for $60-70 USD and seem to be getting more expensive with time.
  
  As for the airbrush, if you have the money and want stuff that works out of the box, then you should just get a kit. There are other vendors (Chicago Airbrush Supply off the top of my head) outside of Amazon that could potentially get you a better deal.
  
  If you are a DIY person and potentially have need of power/air tools in the future, you might want to consider a mini shop compressor. This one by CA air tools is recommended by some people here because it's supposed to be pretty quiet while delivering pancake compressor pressures. The caveat is that you have to be comfortable with buying the right fittings/adapters to make the airbrush/hose work with the compressor.
  
  If you don't have or aren't willing to spend money, then you can just go to Harbor Freight tools and get a compressor, hose, and accessories, then go to Hobby Lobby with a 40% coupon and buy an Iwata Neo or a Badger Patriot 105.
  
  edit: Definitely agree with /u/Funakatown that you generally get what you pay for. If you're really into the hobby, investing in good tools from the beginning is totally worth it. These tools and skills are good not just for gunpla, but all plastic model/miniature hobbies, cosplay, and general DIY. On the flip side though, if you live in an apartment and you never know when you might be moving, or there just isn't much stability in your life now, it's understandable to not invest too much in. Especially since it might be hard to get your money back if you have to sell your stuff down the road because you can't take it all with you. Or you find that you hate airbrushing, which does happen to some people.
