Mad Catz Capcom Arcade Cabinet Fightstick: What's it worth?

I won this Capcom Arcade Cabinet fightstick in an official Capcom-Unity contest earlier this year. I haven't used it whatsoever and I'm looking to sell it, most likely on eBay. How much would/should something like this be worth? As far as I know, there's only one other stick with the "Avenger" art on it, and that'd the the PS3 sister to this X360 stick.

Does anyone around here know what sort of price range I should be able to reasonably ask for something like this? I believe the artwork panel is the only customized part about it, but that has to count for something, right?




Thanks for your help!
