It's kinda nice that you're willing to haggle, but why do you have to gouge? Why set an unprecedented BIN and let it sit there for months? Exactly what service are you providing to humanity by setting up an LLC and buying a kids toy for $100+ and trying to flip it for $500? You're a parasite.
Actually, I probably won't let it sit there for months. I have Retrogaming Expo coming up the end of this month and I will probably pull it and bring it to that event. I sold a majority of my pc engine/tg16 stock at the show last year, and I prefer to sell most of my inventory outside of eBay at events like the Portland Retro Gaming Expo, Midwest Gaming Classic, TooManyGames, Magfest if at all possible. Although it costs about the same as ebay fees when you factor in airfare, hotel, shipping, and table fees, it is way more fun to sell and haggle to people in person and talk about turbo grafx gaming during the slow moments of the show.
Personally, as a fellow Turbo Grafx gamer, if I was going to zero in on "parasites" I would start by policing the forums since you guys cut each other amazing deals and treat each other like family (especially compared to other video game forums). I would be seriously pissed off if there were any businesses using the goodwill of the pcefx forums to gather inventory.
