The benchmark for stainless is 18/10 ratio stainless steel. It's what's recommended for stainless steel cookware. When I actually redo my entire cookware, I'll probably get all stainless, and keep one teflon pan for the few times I make omelettes and some cast iron things. Teflon isn't that heinous by itself, but people have a tendency to hike up the heat to do searing and stir-fries and whatnot, and Teflon simply isn't made for that high-heat cooking. Since omelettes and delicate things (like crepes and pancakes) can't have high heat anyway, it's not an issue. A lot of grills and waffle makers and other things are made with a Teflon coating, and again, Teflon isn't much of an issue unless you need high heat.
I have one good stainless pan at the moment, that I have purchased from TJ Maxx and I'm loving it. It does wonderfully with most one-pan dishes that have some moisture or a bit of sauce. It gets a bit sticky cooking single things like meats and such, but it doesn't seem to burn at all, and with some scrubbing the sticking stuff comes off, it doesn't burn on the goo like teflon does. For things like searing meats, fishes, chicken, etc, you need something like using more extra virgin olive oil or poaching in a little bit of liquid (chicken stock, wine, etc), to keep from sticking.
If there is a TJ Maxx or a TJ Maxx HomeGoods store near you, you can get all this stuff at a discount. I have even gotten a Lodge cast-iron pan from there at a discount. I don't know how to use cast-iron yet, so I haven't ventured to use it yet, but it's pre-seasoned!
