Thanks for the tips. I ended up already buying this one and it should be already at my house today:

I'm not sure yet how I'm going to install it because insulating the lines between hole in the bar countertop and the top of the kegerator looks a bit complicated. I'm actually thinking of just installing the tower right to the kegerator and shimming the bottom of the kegerator until it's as close to the countertop as possible. It will be shorter, but at least it will be sealed. I've seen people use home depot insulation and glue but that isn't very elegant and I don't think it will be very efficient either. That's my only concern at the moment.
