Based on my experience, I wouldn’t spend too much on non-stick pans, as the coatings do get nicked, scratched, and generally become unusable, unlike straight metal or cast iron (enameled or not). They’re fundamentally disposable, albeit on a longer time frame than most disposable things.
We’ve got all four here- a full set of All-Clad stainless, a couple of enameled cast iron dutch ovens and similar things, a couple of old-school cast iron skillets, a couple of non-stick frying pans/skillets, and a non-stick saute pan (higher, straighter sides).
The two non-stick skillets are both T-Fal, and they’re doing very well after a year or so of use. They’re not expensive, relative to say… All-Clad or Calphalon non-stick, but they’re not bargain basement either. The saute pan is some Korean brand we got at H-Mart on a whim. It’s fine, but it’s showing more wear than the T-Fal are.
In the past, I’ve had a couple of those restaurant-style non-stick pans and they’ve been good as well. I had one of those green colored ones that was advertised on TV (same basic ads as the copper ones), and it worked great for a few months, then out of the blue, everything started sticking. So get the normal dark gray/black ones!
The things you have to look for are whether they’re dishwasher safe (some aren’t) and for the thickness of the underlying metal (usu. aluminum). Thicker = better, for the most part, as it distributes and retains the heat better and more evenly.
So I suppose my recommendation would be to aim somewhere in the middle. Not those “as-seen-on-TV” ones or the very cheapest Walmart “Mainstays” pans, but I wouldn’t go for the high-end ones either. I’d go with T-Fal, Tramontina, or KitchenAid, or some other mid-priced brand.
