One vote....
I'll chime in with one vote in favor of these machines. I got ours in Jan 2005 and it's been night-and-day better than the PoS GE Profile plastic tubber we had before. It gets virtually everything clean and shiny (the only exception being cooked-on scrambled eggs, and it managed to get 2/3 of that off!), and runs reasonably quite.
Now, that being said I am on pump #2 after the first one started making an unfortunate loud buzzing noise, so long term reliability could be an issue. Still I'm happy with the purchase.
Are the current KA machines any good, or in the future if I'm staring down a non-warranty repair that costs more than it is worth should I just get a Miele?
