I purchased a basic upright refrigerator through the door from KegCowboy.Com
in early 2006 because they were the least expensive option and the kit is still working great. I went back to them this past spring to build my homebrew kegerator and was amazed by how much lower the price was compared to every other option I saw. The dual product regulator I purchased was $25 less than the next lowest option. I think they are a good company and would recomend them.
