Would say Benchmade mini-Griptilian would be best bet, but it would be over your price range. You'd probably be able to shop around and get it to be under $80, but there's still shipping and applicable tax. Otherwise, Benchmade mini-Presidio might be a little bit cheaper, but not by much.
Otherwise, Spyderco Delica.
Haven't been in the Kershaw area for awhile that isn't non-assisted, but i still have my Vapor from awhile back that is my backup knife.
