From time to time I consider getting one. I feel that the set and forget method is superior, but it sucks when you have a keg blow and you have to wait a week or two to drink it. True, I have 6 other taps to choose from, but I'm greedy and want all taps funtioning!
Aging isn't really a concern for me since my pipeline is so deep at this point - anything that makes it into the Keezer is well aged before it goes in.
All that being said, I'll probably never bother with one.
