They don't make yours Campfire cast iron anymore from what I could see. Are they enamel inside?
Some of my saute / fry pans were non-stick Teflon, most are black and I have two white enamel sauce pans. The black is better for higher heats. Non stick teflon and heat do not get along well from my experience so I walnut blasted the interiors. They were enamel underneath. Even the pans I had overheated cleaned up great. Once I had polished them up (a little 2000 wet sanding) and a little seasoning, they have worked great for years. If you have high end Teflon cookware, I highly suggest this. It was just a few bucks a piece.
I had a LC square grill pan but I never liked it (I burned them up) so I gave it to the SO's daughter who used it all the time. since she got along with it so well and I didn't use it, it now is hers.
At a farmers sale I found an old school, no name, cast iron HD griill pan, a 12-13lb beast, for like $10 that I sit it directly in coals or on a grill grate. Nothing fancy but gets the job done. The SO banned it to the garage after it's first time of use. It's been walnut blasted twice .
I am now eying a LC oblong grill pan for inside but with enamel surface now that they have dropped from over $200 to $130. ($60 on Ebay.*)
FMB has been trying to talk me into Sous Vide cooking and this will be a killer pan for searing meat.
*Looks like I may have found one
