A solid, cheap one from the restaurant supply store. Something like this. Or if you insist on a stainless exterior, this. Don't think of it as an investment. If you take good care of it, it will last a few years, but it's eventually going into the recycling bin. Teflon coatings just don't keep their performance forever. The difference in durability between the cheapest ones and the fanciest ceramic /diamond studded ones isn't what you might think. Those additives help protect against physical abuse, but not against the gradual breakdown from cooking and washing that all the nonstick surfaces suffer. I cry when I see things like $500 copper pans with a teflon interior.
The pans will last by far the longest if you use just for what they're good for, which is eggs, and other things that are genuinely sticky and that don't ever cook on high heat. Don't use the pans for things that need a hard sear. Doing so is bad for the pan and bad for your results.
Edited to add: I'm talking purely about teflon, not anodized. Anodized surfaces are not non-stick.
