Dan, I have been running an Igloo 6.0 for over a year. Overall I am happy with it. Regulator was broke from day one, but after buying a Micromatic regulator I have been happy. Anyway, I really want to convert to a 2 tap setup and was interested in some pics, info,& advice on your tower conversion. I was going to buy a 3 inch stainless tower with perlicks but would rather not modify the fridge itself unless there is no other option.
