I have no clue about built in.

I never had a fridge w/ an ice maker, but I LOVE crushed ice in a drink instead of cubes. So if I'm gonna drop some dough on a fridge, I'll go with a scratch & dent, and get the ice maker.

Whenever I break down and re do my kitchen, I'm going to put as much commercial stuff in as possible. I'd love to have a fridge only, then a 5' freezer/worktable on the one wall, w/ a cutting board top. Above it, a rack to hang the pots.
