You're one click away from reviews on Epinions and HowStuffWorks. I'd say the same for CNet, except the first 3 dishwashers I clicked had no reviews, just a template dishwasher buying guide, and so I gave up. Of those three, only CNet comes close to spammy... but CNet's dishwasher buying guide is at least decently written.
I haven't found any reviews yet on Epinions, and I've clicked more than three times. They do have a nice side-by-side feature comparison feature, but reviews appear to be entirely user-driven so if no one has posted a review you won't find one.
