Your references, pictures, and detailed description are all very nice, but you'd do well to rethink your pricing. Most members here help each other out and are very quick to criticize any perceived price gouging (in fact, we have a perpetual thread about it). A lot of new, often well-intended, sellers show up thinking the prices they've seen on ebay are an accurate guideline and they tend to get run out of town pretty damn fast.
I bought a complete w/poster copy for $80 sometime around 2007 and that was on ebay. You could probably get over a hundred now, even on these forums. Accept reasonable offers and you'll find a warmer welcome and good deals returned in the future (like free Sapphire reprints). Stick to the ebay mindset you might as well move along.
