i have 3 major hesitations w kegerators
1 - i like a ton of variety and not sure i could stick with one brand for weeks at a time
2 - cleaning ... is probably a pain in the butt. half the bars you go to have dirty lines. ruins the beer.
3 - stale beer? im not sure if this is a valid concern but id be weary of a kegerator keeping a half barrel fresh for a month.
