Why do my baking sheets sometimes buckle in the oven? I thought they were just old and replaced them, but now the new ones are doing the same thing!
Am I going too cheap on the baking sheets or is there another reason?

Chris, we can't speak for your current baking sheets, but our hunch is that you went with too thin sheets. You don't need to spend a fortune, though, to get good-quality baking sheets! Look for professional, heavy-gauge aluminum sheets like these:
• Norpro Professional 9-Inch by 12-Inch Heavy Gauge Cookie Sheet
, $10.88 at Amazon
These last a lifetime, and can be found very inexpensively at restaurant supply stores. I have a couple of these, and they never buckle or warp. They don't have a nonstick coating, but with baking spray or parchment I never have any problems with things sticking.
Readers, any more suggestions for Chris?
