Wow, you guys are amazing at coming up with data and info besides all the personal experience!  The teflon info was informative..good to about 600* is good.  DD, the oven I have is the Svante Freden which is on the small side of the reflector oven spectrum.  I too have a couple of the GSI square fry pans but in my oven there's not enough depth to rotate well.  I put one of my wife's round 9" pie dish in and seemed to hang out in front a bit too far to suit me, I'd hate to see a fancy desert tumble into the fire  :'(.  An 8" to 8 1/2" overall diameter looks like it would be a good fit.  So now the hard anodized fry pan at WalMart is looking better.  I'll just drill out the rivets.
