It costs $260 to get one from a verified ZT dealer. The 0560s are easy enough to tell if they're legit, and you have the added bonus of being able to check out the action before paying for it. Someone new complains every day about the detents being too tight or the lockbar sticking - so being able to handle the knife before purchasing is worth the 10$ you would save anyway. On some of the lowball sites their pictures have discrepencies on some of the models, and so far everyone I know that has bought from budget sites are striking out with the fit and finish.
3 blemishes would bother me though - I have an 0561 I have opened 200 times and carried in my back pocket, and other than a little bit of stickiness on the lockbar you can't tell it's used at all. What you should do OP, is go and check out the knife under bright lights and look it over carefully. Check the detent strength and make sure the action is smooth - see if you can open with the flipper and the thumb stud. If you think it's practically new and the action suits you, jump on it - you can buy a half dozen more and not find one that suits you. If it has easily visible blemishes, the action isn't smooth, the lockbar sticks or the detent strength doesn't suit you, try your luck somewhere else.
