Seeing that you have stretched the ten minutes out by posting here, what satisfaction did you get from anything beyond the first warning about the seller? I agree that he was playing the system, he was getting burned and cut his losses. If you get some type of satisfaction from carrying a grudge to extremes, I suppose this method will give you a warm-fuzzy.
I agree with the replies to move on, other than a potential ulcer from stress you aren't going to get much from going any further. ebay has become too crowded with people convinced they have a RARE, EXCLUSIVE, ETC. item that they will make a killing from, usually its pure crap, or something close in its olfactory stimulation. You seem pretty knowledgeable about cycling and what makes a good Rando ride, channel your energies into productive riding activities. JMWO.
