any thoughts on home wine refrigerators? I've put wine-rack shelving in an interior room (NOT a basement) but am thinking that more consistent temps, and lower summertime temps, would be good for the handful of good bottles I've got, and I also think it'd be nice to keep some whites chilled so I can make last-minute pre-dinner decisions about what to drink that aren't driven by what I remembered to put in the fridge. So how useful or important is it to have dual-zone controls? what about other features - slide-out shelves, interior lights, etc. - how important are they? are flat shelves better than contoured? should I worry about warranties (do these things break down a lot)? any brands people like or don't like?
