Secondly, I understand the desire to insulate yourself from bad transactions, but your numerous rules and warnings about restricting certain bidders, non-paying bidders, negative feedback, no personal checks, etc are worded and presented in such a manner as to create a rather negative vibe. Cumulatively, they give a harsh "don't mess with me" impression that could turn off potential buyers. A more buyer-friendly atmosphere could turn more lookers into buyers.
Hope some of this helps, because you have a good product, good description, nice template - it should sell.
