Last year I retired my huge honkin 6 tap "keezer" and picked up a used commercial unit keggerator with three taps that can hold 3 sixtels. Got it home and the compressor was blown, which sucked. Got the guy you sold it to me to go in on the compressor with me (he paid 2/3rds) and am pretty pleased. The nice thing about the commercial units is that you can just replace the compressor rather than the whole keggerator. Hopefully I won't have to do that for quite some time though!
