I've used a number of different pots/furnaces, but have settled on two 10# LEE bottom-pours. There were times in the past when they may have caused me issues and I didn't know it was the pot, but I've gotten to know them well and they work fine for everything from 50 grain .225" to 265 grain .432". They're cheap, they're compact, uncomplicated and they work. I use a home-made PID setup from scrounged parts on one. Not saying i's the best - I tend to minimize and see just how little I can get away with, but I have been happy with them.
