Reddit mentions of Sandisk SDSDQM-016G - B35A 16GB MicroSDHC Memory Card, Class 4 (RETAIL PACKAGE),Black

The class numbers roughly correlate with how many Megabytes per second they can transfer. So class 2 can transfer about 2 MB/s, class 4 about 4 MB/s.

In all honesty, a good Sandisk class 4 should be sufficient. You can buy a 16GB class 4 sandisk MicroSD for $9.25 and free shipping.

Of course, if you want faster speeds, go for a higher class, but the only issue I can think of class 4 MicroSD's having is being having to wait about .7 seconds between taking photos while the photo is written to the card. Also class 4's won't give you amazing fast transfer speeds.(you get 4 MB/s)

Did you not read the developer spec sheet before you bought your machine?

Of more serious concern is the fact that 32GB can be had for half the cost in two 16GB cards.

I'm gonna wait until the 128GB cards come out to buy a 32GB card.

Well, I might cave at 64GB. Point is it isn't worth $200.

I just recently got one from Ebay, you can try there. I'm sure the preowned from Gamestop are fine as well.

As far as memory..my recommendation is to pick up (2) of these http://www.amazon.com/Sandisk-16GB-MicroSDHC-Memory-Class/dp/B001F7AJKI/ref=sr_1_1?ie=UTF8&qid=1334935355&sr=8-1
and (1) of these http://www.amazon.com/MicroSD-MicroSDHC-Adapter-Converts-Cards/dp/B001RPEJA4/ref=sr_1_1?s=electronics&ie=UTF8&qid=1334935402&sr=1-1
this will work great in the PSP 3000 and will save you alot of money as compared to just getting a 32gb pro duo card.

You can get a PSP 3000 used and in great condition on ebay for as low as $60. If you don't care about finding the best deal, you could easily find one at an average price of $80. From there, you can go on Amazon and get a 32 GB memory stick in the form of a dual-adapter that combines two 16 GB microSD cards into one stick. Even if you stop playing your PSP, you'll still have two 16 GB microSD cards to use for a phone, camera, computer, etc.

Anyways, so it'll come out to about $100. I've done software mods for a fair amount of electronics and I have to say that the PSP is by far the easiest. It's an extremely fast and simple mod that can be reversed at any time by simply restarting the system. It can then be reapplied by running a file that literally just restarts the console as modded.

You can play NES, SNES, GB, GBA, Sega Genesis, Sega Saturn, Sega CD, PSP, PSX, and more. I played a bunch of GBA, GB, and SNES games on mine and they all ran flawlessly. You can keep the games at their original resolution, fit it to screen, stretch it, or anything else you want. It's awesome. You can even play PSX games perfectly. I played a bunch of Vagrant Story, Chrono Cross, and Tomba. Don't forget that you can obviously play anything in the PSP library too. They're uploaded all over the place and you literally just copy/paste them into the Games folder on your memory stick, and they run perfectly.

Seriously, if you want to play emulators on-the-go or even chilling on your couch, get a PSP 3000 on ebay. The screen is nice and big, the buttons are comfy, and everything is simple when it comes to software modification. Here's the basic mod. For $100, it's an awesome setup and I highly recommend it.

Edit: I almost forget to mention that you can use a computer monitor as the display for the PSP if you want. I never cared to, so I can't say whether it's simple to set up or comfortable.

I have an 8GB in my 60CSx. Around 5GB is taken up by the street nav. maps for all of North America, with a few topo maps of Maine.

You can get a SanDisk 16GB for $12.65. An 8GB is only $8.

that was not microSD.

I went with an adapter with 2 slots, and it actually seems to do something similar to RAID-0 (striping), so it ends up with double the performance that 2 cards would have (tested that against a 1-card adapter that I bought before).

You're also better off going with a Sandisk at class 4 speed. In my experience, class 6 and up don't handle small data transfers as well, but class 4 should give more performance than class 2.

A Sandisk Class 4 microSDHC isn't going to cost you much more, but you should be able to squeeze a better speed out of it.

Just a 16gb sandisk micro sd. It holds about 4 hours worth. The battery only last about 2 hours.

Yeah. You can download updates and even download games directly.

If you're going to buy that bundle, I suggest getting the micro-SD card off Amazon. I use 8 GB in this and 16 GB in my phone.

However, since 16 GB's are now 2.24, I think it's more worth it to buy those. The biggest DS games are 128 MB each, all save files are 1 KB I believe, and the biggest 3DS games are 512 MB.

This with this or this.

It can be put together for under $60

>I only have so much space on my memory card.

you wouldn't even need to say this if they didn't charge out the ass for their proprietary memory cards. normal mini sd cards cost half the cost for twice the space literally. see plain here and Sony here.

Depends on your microSD card reading speed. You'll want to look at the high-range ones to read large 1080p / 3D movies. Here's an example of a class 10 straight from Amazon for reference. Otherwise some of the lower end microSD cards, while they can hold a lot, are not going to read a 1080p file fast enough to make it run clearly or well. Here's an example of a class 4 which will not run those files well.
