We're going to put in a dedicated bar, and one of the appliances we'd like is an ice maker. I'm sure I'm not the only chowhound who wants symmetrically shaped ice for even melting (round, cube, octagonal, etc...just not crescents or rectangles), and ice that's "clear" meaning the minerals and dissolved oxygen have been removed.
Marvel has a clear cube maker, manitowoc has a cube maker, and an octagon maker, Scotsman has a "half dice" maker...
Others are GE, Franklin, Kitchenaid, but I haven't figured out exactly what type of cube they make.
The guy at the local appliance store warned me away from U-Line, which apparently has some pretty bad reliability problems right now.
