I bought an LG that is great for cleaning not at drying. It doesn't have a vent to let the dishes air dry you have to wait for all the water to condense to the bottom. I gifted it to my brother & spent a little more at Standard TV & Appliance & bought an Asko. There is no comparison, The asko gave me everyhting I wanted & some things I didn't even know I could have. I love it like a second child. For my kitchen remodel I added one more, now I have two. I really love them, they make cleaning up a breeze. They clean well, they dry great, they do it quickly, quietly (les than 45 Dbl) & they use less water & energy than the LG which was already an energy star appliance. There is a video on Utube if you look it up. I am told by some of the German moms in my mom's group they last forever.
I have seen some negative feedback on the Asko's, I think they have gotten better with time. I have had mine since January 2009. I had the LG for 18 months.
The big thing I wanted when I bought a dishwasher was the element to be covered, so if any plastic fell it would not melt & stink, both the LG & Asko I bought have that feature. Anything that runs under 50 decibles will be very quite.
Meile is another brand I have heard good things about & was looking at for my kitchen. Both cost a little more Than you are willing to spend.
