<<...I'm in the market for a good locking folder....My price range is about $75. Ideas?>>

Depends on what size knife you want. I bought myself a Kershaw Silver Spur ($21.95 from KnifeCenter.com), a tiny little knife with a locking blade. It's about the same size as a SAK Classic, but it feels very sturdy. It became my favorite blade. I carry it always. It fits anywhere on my person (watch pocket of jeans, pocket of dress shirts) and I can deploy it with minimal fuss. Very sharp, too. I also bought its big brother, the Kershaw Silver Spur II.
