Genuine commercial gear is certainly intriguing, but then you don't get features like the ice cube maker, water in the door, and so forth. You just get a large box with wire-rack shelves. Viking, Thermador, and others offer product lines that are competitive with SubZero in every way (including insane prices).

The GE Profile 48" model appears to have a street price of around $5800, versus $9500 for the "equivalent" Sub-Zero, after steep discounting. That was on my list, early on, but it seems to have the chimp problem in spades. You look the thing over, and what you see is not all that different from the cheaper, junkier GE models. Kinda like looking in a Chevy Corvette and seeing the same crappy plastic buttons that you find in a Chevy Cobalt.
