Hello, thanks for the reply. I do plan on moving on to a gas burner, but at the moment, I am (slowly) brewing on my electric stovetop. Would a keggle be practical for this use? I've never really examined the bottom of a commercial keg. If I can squeeze a batch or two out on the stovetop with one I would be interested in an old keggle as well, so maybe if you've upgraded your system to some Blichmann Bling and have an old pot/keggle with thermometer and ball valve, I would love to take it off your hands!
