Stoneline Frying Pans -- Are They Worth It?

I cook.  I don't mean a little.  I mean a lot.  Those that know me also know that among other things I'm a Lunch Lady (well, okay... technically a Lunch Man), a caterer, and general all around foodie.  When I saw the infomercial on the Stoneline pans, I had to look into it a bit further.  I mean, how different can they be from other non-stick pans, right?
