I have been using a 9 gallon cheap turkey fryer and pot and wanting to upgrade to stainless steel brew pot. Im trying to obviously get the best for my money and would ultimately like to get a 2 hole pot, one for ball valve and one for thermometer. May turn it into a mash tun at somepoint or get a 2nd one. What pot do you recommend? Don't plan on doing over 5 gallon batches anytime soon. Have read about spike brewing, and my lhbs has polarware.
