Magic Chef HMBR440BE - Only got that one because it was the one on Craig's List. The one I bid on first was sold. If you don't mind the possibility of a couple of scratches shouldn't take more than a couple of weeks tops to find on Craig's List and save $100+ .
Just got a 4.5 size off of craig's list. The 7 gallon Fermonster will fit, I just need to cut the inside of the door as there is a part sticking out down the center to hold shelves I'm obviously not going to use. Thinking quick dremel and duct tape and I'm done. I don't think an airlock will fit...
