Your getting a deal either way. CRK are worth every penny as far as I am concerned. I usually buy new, but have gotten many that were second hand, but still new in the box and alot cheaper than new. It just depends on what your looking for. If you just want a plain one, you can get some deals if you just look and are patient, in time the perfect one for you falls right into your lap. As far as what to look for when used, I always check out the edge and the lock-up. I like lock-up about 50%. As for the edge, I just wanna make sure someone did not butcher it while sharpening it. A used one will almost always have scuffs on the clip, so thats normal. Good Luck looking and have fun while doing so. Let us know what you decide ????
