You know, I think I've seen them with freezers on top but I always figured I'm in the fridge portion way more often than the freezer so it's more convenient for me with fridge on top. But I know they have some great new designs anymore so I definitely would check them all out.
My next will most likely be stainless unless they come up with something I like better. I've had white, off white...and yes even...avocado green
now I've got a black one and like it, just think the stainless would be easier to clean - I love my stainless sink!
