isnt it a better question to ask what he wants for it? then ask yourself what you wanna pay for it
I think its hard to value SI, so many guys bag it out, others luv it for the artwork alone.
If I had 1500, and the guy was happy to take it....fine. 2k? well its in good nick, and could get that much. THEN sum1 maybe happy to pay 3k lol
that help? lol
