-If you are un-realistic about what you are asking, the price police will swoop in and bust you. FWIW, they are usually big, if not bigger, JONG's than you. cracking on a newb cause he wants $50 more than you think his stuff is worth don't make you cool, ace. don't worry about the price police, but following the above guide (guide not RULE), will yield a better chance at a sale.
