Very few non-stick pans are dishwasher safe. I'm sure you know that. :-)
There's a fairly good article on cookware from December 2005 at [link|http://www.consumerreports.org/cro/home-garden/cooking-cleaning/cookware-1205/cr-quick-recommendations/index.htm|Consumer Reports]. You may need to have a subscription to read it though.
Cheers,
