We bought a set made by the Swedish company ASKO. They are wonderful! My wife swears that when we move, those are coming with us to our next house. They are expensive but they work great. We easily do 15 loads a week and they have just kept humming along for the 7 years we've had them, with no sign of them wearing out soon.
I have to second the 'stay away from Maytag' chorus I've been hearing. We replaced our old Maytag dishwasher with a new one 3 years ago, and not only have 2 major parts gone bad, it does a worse job cleaning that the 20 year old one it replaced. As long as American durable goods are designed by cost accountants to die on cue after 3-5 years, this country will lose market share to people who remember how to build quality. Saving $500 on an appliance doesn't help you if you have to buy 3 of them to equal the life you get out of a better built unit.
Oh yeah, and Sears blows! Anything they sell on clearance, or marked down, demo, or 'discontinued' has either been in someones house already, or is defective from the factory, or both. Don't trust Sears to be anything but deceitful when it comes to 'sale' items.
