My favorite dishwasher was a Kitchen Aid, which was around $600 on sale. It had the stainless interior and separate motors ect. Cleaned so well when we moved we bought the same one. However, THAT one had problems..... For the new, new house we bought a Bosch. $350 for a stripped-down version. Stainless sides and a poly-base. No disposer because they're illegal in Europe but for some reason we don't need one in this machine. Just a screen/filter that you lift out in case anything collects. Also, NO ESPOSED HEATING ELEMENT TO COOK PLASTIC ITEMS

! I'm pretty happy with the dishwasher.
The premium for stainless steel is worth it. Quieter, holds the heat so heated drying isn't neccesary, and the inside doesnt' get stinky becasue the stainless doesnt' absorb odors like a plastic one does.
