Avoid any that use a filter instead of a macerator. Those things trap particles and get stinky pretty much every wash. I ended up cutting the mesh out of mine (that's what causes the stink). The rest of the filter is fine enough to prevent clogs, and it drains into the garbage disposal anyway.

Check out the cycles on any you're considering. Lower pressure spraying is one way they reduce noise which makes them generally less effective, so longer cycles are required. I've seen a Bosch with a 3 hour cycle. To it's credit it was very quiet. It may have had a shorter cycle available, it wasnt mine so I never looked.

My current dishwasher is the cheap kind - I just don't believe a box that sprays water needs to be fancy or expensive. It works fine, and we use it hard, as in 1-3 times per day (lots of cooking and prep).

It's probably 70% quieter than the previous ancient one. You can get quieter ones (like that Bosch) and that's where spending more makes a difference.
