I have two of the Kershaw Emerson's (6034 and 6034T), and for the price I paid ($25 each) they're a GREAT knife. For the price.
I'll be another one lobbying for the Buck 110. I love that knife, full stop. I just ordered 2 from the custom shop (neither is under $50 of course, but the original is what sold me, so there it is).
