This my opinion, others will have theirs. All of this is contingent on your brewing desire and longevity in the hobby. I would purchase nothing under 15 gallons. Saves you with boil over, and can grow with you if you desire. I started with a 10 gallon Polarware. I use it for almost nothing. I thought I would only do 5 gallon batches. That didn't last long, and a double batch will not fit in a 10 gallon vessel. I would buy a kettle that is of triclad construction, and induction capable. Only way I would go is with welded fittings. I would also prefer to have welded handles w/o rivets inside. That is hard to find, but we are dreaming right? I would want fittings for a ball-valve, thermometer, whirlpool/recirculating. You may or may not have a pump. If you don't, and you get serious, you will. I don't have a sight gauge and could care less about that. I personally would put my money in my kettle. I don't know your funds situation. I'd rather have a killer kettle than a stainless fermenter. Id love to have a nice 1/2bbl fermenter. I ferment in 15 gallon plastic barres w a screw top lid. Love them and never have had an issue.
