One thing to consider if you don’t NEED a whole new set:
Start building a really nice set one piece at a time.
Stainless = slick/non stick when used right + great deglazing etc.
Aluminum = even heat distribution
Copper = heat conductor/retention
(I think I got those right – it’s been a while)
Smush ‘em all together and you get an All-Clad Copper Core fry pan.
Holly crap those things are nice. I splurged and got my wife one for her birthday a few years back (a $200 fry pan? I must be nuts!). She loved it and was hooked, so I was a set for birthday/xmas etc for quite a while as she just wanted more copper core stuff.
Those things are more slick than any coated/teflon/non stick pan in existance when used properly. (you gotta know the little tricks though – like heat it up on medium for 30 seconds, add few drops of oil, you’re good to go). They go right in the oven too and are great for all the deglaze etc techniques mentioned so far.
I use to be a big fan of cast iron (hey, at $20 vs $150 who wouldn’t!), and we had an analon set, but at this point we’ve replace just about everything with all clad copper core.
Over time you end up with a some big $$ spent on cookware, so if you aren’t really into cooking it might not be justified, but I’d still recommend splurging on a least one of their fry pans - just for fun - at some point. Oh yeah – made in USA!!

This one's my personal favorite:
