Sound suspiciously like a CAMILLUS EDC to me. (Available in 420HC - $50, 154CM - $50, D2 - $70, or Talonite - $160)
Camillus customer support simply CANNOT BE BEAT in a major production company - and it's a tough little knife. It's got a plenty strong frame lock, good ergos, great balance, and the blade length is apx. 3.125" (I dunno how anyone ever came up with a sub-3" measurement, no matter what weird position I put it in, it always comes alot closer to 3.125" on my 154CM EDC) with a very pleasant recurve. Also Camillus is kinda famous for fantastic heat treats, making pretty much any steel they use perform better than it does in many competing manufacturers.
Another one that hit me, if you are willing to tolerate AUS-8A, maybe you should go looking for a Spyderco Micarta Calypso Jr., it isn't made of a "premium" and it's blade length is only 2 7/8" I believe, but it's a solid lil lock back with some great handles - the plainedge variants are becoming quite rare as well, so if you wanted one i'd try the BF Knife Exchange before anything else (not even John F. Jensen is selling PE Micarta Calypso Jr.s anymore).
Also by the way, the Ti Salsas use ATS-34.
If you want to go to the upper end of your price spectrum, check out a Benchmade 720 or 721 (depending on whether your prefer T-6 Aluminum or G-10.), I found this to be a very ergonomically pleasing knife with the totally awesome axis lock... I believe it is around 3 1/4" in blade length.
It's your call.
