You didn't mention if you are a DIY kind of guy but being a brewer I'll bet you are.. the two just seem to go together. This is going to be a long response.
Brewpot
Brewpots can be very expensive or relatively cheap. If you can get your hands on a keg, make it a brew pot. There is info on this site and youtube on how to do that. All you really need is something to cut out the top and drill a hole or two. I bought an angle grinder and a step drill bit kit from Harbor Freight for around 30 bucks total, just for the project. But I had a keg. Bought a kit from a vender on this site Bobby_M that included a sight glass/thermometer. I don't remember the exact price but it was very reasonable and works perfectly. Also a $35 stainless steel, weldless 1/2" ballvalve from Morebeer.

Burner
The burner you showed is very nice and seems like a good price. I don't think you would be dissapointed with it. Bayou classic turkey fryers are cheaper and I never had a problem getting my keggle up to temp with one, however I did have to build a frame out of an old metal bed frame to support the keg. It was not hard to do but metal bed frames are extremely tough. Cutting it was no problem with the angle grinder I used on the keggle but I drilled 28 holes and it just chewed up drilled bits. I don't think I'd recommend doing that. If you weld or know somebody who does and would do it cheaply it might be worth it. Bayou classic makes a burner

Wort chiller
I built a counterflow using 20' of 3/8"OD copper tubing and a 5/8" garden hose. It works, but slowly. When I have the money I'm going to buy this

Fermentation chamber
A lot of guys have suggested a fermentation chamber. If you can find an old frige or deepfreezer cheaply and you have the room for it, then you could buy a temp controller for about 50-60 bucks and make it a fermentation chamber. If you can't find a cheap frige or freezer or don't have the room for it, don't sweat it... not at this point. There are other ways to keep your wort fermenting at cool temps. Ie., A container large enough to put your carboy in; fill it with water and ice, frozen soda bottles that you can reuse. Throw a wet towel around the carboy that drapes into the water and have a fan blowing on it to help evaporate the heat from the wort. Not the prettiest thing, not fancy, but it will keep your wort cool and aside from a container large enough to put the carboy/bucket in you probably already have the rest of the stuff. Me personally, my two cents. You don't need to dedicate your money in a ferm chamber at this point. Others might feel differently but you have a 700 dollar budget.. later you can spend the money on one.. Just not a necessity right now.
Keggerator!!!!!



I would spend a bulk of the money on a keggerator and 2 or three ballock corny kegs. Pinlocks are cheaper.. I have some and they are a pain to get a good seal at the pressure in port. Just my 2 cents. I'm sure other people use them without problem. Don't buy a brand new keggerator, one of those small sized friges with a tower. I ordered one once; I think it was from beverage factory. Was about 400 dollars, free shipping. I ended up cancelling the order with no hassle from that company. I think it was BF but may be wrong. Anyway don't waste money on one of those things. Build your own keggerator. A good way to spend your money on a keggerator is to find a frige on CL or classified adds and then buy a kit something like this one.

When you decide to go all grain make your own mash/lauter tun out of cooler. Buy a refractometer they are really nice to have. You can take a sample of the wort... just a few drops needed to check the gravity.. Coolest thing ever. Also buy a grain crusher of some sort so you can control the crush instead of getting it pre-crushed from your local home brew store. Plus with uncrushed grain you can buy in bulk and store it until you are ready to use. I have a barley crusher with 7lb hopper. Very happy with.
Ok, I guess that's it from my experience. Congratulations on your winnings! Good luck on your brewery set-up! Please let everybody know what you decide to do.
Cheers!
