Screw the small claims, it isn't worth the stress for $170....just be thankfull it will be another 20 years at least before he crosses your path again, if ever.
I bought a Nikon SLR off ebay for my daughter at xmas....$435, had it mailed with insurance...well, it got lost after it hit customs (likely a nice xmas present for the delivery driver).
The sender neglected to keep his receipt with the insurance proof etc and now I am out the money according to him, as the delivery tracking says it entered Canada...and so no need for him to supply me receipt, anything...well how the H$ll am I supposed to get insurance you freakin idiot!!!....anyone in Ohio?, I have a [censored] available there!!!
OK, now I've vented...I may as well kiss it goodbye as well....
