We snagged a 15 gallon one of these
off the classified and are loving it so far (2 batches in).
Our first batch we opened the lid a few times to check it out and a wild yeast got in
The second batch was a 10 gallon porter and the entire brew club was there for the brewing and the kegging.
It was dead easy to use for both ends of the process. It breaks up for cleaning in our shower and stores perfectly under the stairs so it stays warm. Since it is plastic it also doesn't weigh a ton, I can move it around all on my own.
I am thinking about doing a mead in it while the hubby is out of town
