I have four of the 8000 series pans: 6 x 1.5, 9 x 1.5, 12 x 1.5, and 14 x 2. If you are worried about buying these pans because you think they might melt, stop worrying. The first thing I did with my pans was season them in a grill at temperatures that probably reached well over 500 degrees at times. (Here's a blog post about how I seasoned these pans, with pictures
.) Also, I recently put the 6" pan in the grill with all the burners on high for quite a while, at 600 or 700 degrees, to unseason the pan after the initial seasoning began to peel off. The pan is fine and has since been re-seasoned.
For all the pans that were available in depths of either 1.5" or 2", I chose 1.5". However, if I felt the need to buy more of these pans, I think I'd probably order them all in 2" depths because 1.5" pans don't really work for stuffed pizza.
