I just put in a mid-line Kenmore tall tub. Its quiet and cleans well. Clearance underneath is tight, but it gives you huge space inside. Stainless looks nice but don't get it because you think the machine will last longer. All the other components are the same as a plastic tub model and hence will wear out just the same. Make sure you get nylon racks which are tougher than the PVC-coated ones.
