I have a SoF chamber for sale that I've only used once. It works great, I found out that I do just as well with other methods and am moving towards a keezer for lagering. I don't have a pic at the moment, but it 2" thick pink styrofoam walls that are lined at the joints with weather stripping. Included a thermomstat w/ temp probe as well as the cpu fan to move the cold air. It is nearly identical to the one in this thread, but with added microbrew stickers $40. I'm in the Charlotte, NC area.
