I bought the Bosch Evolution 300 at Lowes and it happened to be on (an unadvertised) sale at that time. With the additional 10% mover's rebate I paid around $430 (sticker price is $578 I think) for it. It doesn't have all the bells and whistles of the high-end models, but it works great and is quieter than most DWs that have the food grinder. I don't pre-rinse anything and everything (besides baked on egg) comes out sparkly clean. I use 1 TBS of Cascade Complete per cycle and don't have any problems with bad smells.
For this price it really is a great DW. I have used GE, Kenmore and Maytag DWs and I like the Bosch a lot better.
Hope this helps.
