Purchase a 5.5 gallon pot you want but without anything added to it.

Then purchase a step bit: https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Dlawngarden&field-keywords=step+bit

Make sure it has the correct size.

Then purchase this bit for drilling pilot holes in metal: https://www.amazon.com/Century-Drill-Tool-26208-Cobalt/dp/B004UUFAYW/ref=sr_1_1?s=industrial&ie=UTF8&qid=1481229448&sr=1-1&keywords=1%2F8+stainless+steel+cutting+bit

Drill the pilot holes where you want the ball valve and thermometer, then use the step bit to widen the hole to the correct size.

I have been using this exact setup with an 8 gallon pot for 5+ years and it doesn't leak one little bit. Also you can choose whatever size pot you want, just remember that you should probably leave the thermometer at least an inch or so from the bottom and keep in mind the bottom water will be hotter than the top.

The biggest mistake I made was not getting big enough equipment to grow. I would recommend going for a 52 quart cooler, bazooka screen and 2 valves - 1 for the mash tun and 1 for the boiling kettle . 1/2" silicone tubing - once you use this tubing you'll never go back. Definitely a gas burner and also some sort of fermentation control

That's actually not bad but as mentioned below, a decent pot will go a long way. I bought a 30quart turkey fryer and put in a ball valve and that's been one of the best upgrades I've made. I have a fermentor now, but I got some free 6+ gallon food grade icing buckets from my grocery's bakery. Spigots, air locks, and bottling wands are $6 on Amazon. Tubing can be found pretty cheap online or at LHBS/hardware store.

Kettle - $25

Ball Valve - $22

Bazooka Screen - $9

Spigot - $6

Airlocks - $7

BIAB Bag - $5

Bottling Wand - $5

Capper with Caps - $18

Various Tubing - $15

This doesn't include your first beer kit, but you can pull off an all grain BIAB as long as you've got fire. My second favorite piece I own is my mash tun which is just a 10 gallon cooler with a bazooka screen and ball valve. I don't bottle anymore, but I feel like if I were to do it again that's all I would need to start. Oh, and a thermometer and some StarSan.
