Also, do you recommend a stainless steel tub?
Stainless steel tubs are good for a few reasons: slightly better drying, no stains (duh!), looks great, no corrosion, more durable overall. Stainless can, however, increase the price, and many models by American brands will not have stainless steel tubs in the price range you're looking at. They're still great machines, though, so don't feel short-changed if you choose a plastic tub. Fortunately, in your price range, racks will be nylon, and that's a much bigger deal than a stainless tub (as anyone who's had the nubs break off of the tines and get all rusty and nasty knows!).
In your price range, a stainless tub would have to be a Bosch. There are a couple models that Sears carries in that range, including the Sears-exclusive Ascenta. The tubs are less spacious because of the European condensation drying system. Here comes your lesson for the night!
American brands (Whirlpool/GE/Frigidaire) use an exposed element to heat the water, air, and dishes inside the dishwasher to turn the water to vapor. That vapor either escapes through vents on the front or condenses on the walls and drains out the bottom (these dishwashers will have vents on the top surface, and the vents only allow fresh air in after a few hours post-drying).
Foreign brands (Bosch/LG) use a concealed element to heat the water in the final rinse. Fresh air is then circulated between the outer and inner walls of the tub. This lowers the temperature of the tub (which must be made of stainless steel to achieve a low enough temperature, which is why Bosch always has stainless tubs) and encourages condensation of the hot water onto the cool walls. The water drips down and drains out the bottom. You are then required to open the door to allow fresh air into the inside of the tub, completing the drying process.
These dishwashers also have a triple-filtration system instead of a grinder-disposal, which increases energy and water efficiency and reduces noise. If you'd like to see a Kenmore model with the same filtration feature, see 13882, which is just a little more than the price range you were asking for. Dishwashers with this filtration system are around 52 decibels on average, versus around 58 for grinder-disposals (6 decibels is two noticeable sound levels, or whisper versus conversation level). Cleaning performance, however, is in no way compromised.
Because of the need for air space for the drying system, Bosch and other foreign brands have smaller tubs. The condensation drying system does use slightly less energy overall, so if total efficiency is a big factor, check out 17272 (which is the Sears-exclusive Ascenta) and 17112.
I hope this hasn't been overwhelming for you. I know it's a lot of information all at once. Hopefully, it will help you make a decision you can be happy about. Good luck!
