I have one around here somewhere. Its still in the package. I would probably include the "See it. Touch it. Play it." t-shirt Nintendo was giving out at their booth too (never worn). I will look around and let you know if I can track it down.
I have a couple of them, but I'd only let them go for the right price. I doubt you guys want to pay that much, but if you do PM me . I'd say I'm looking for upwards of $40+.
Nintendo gave away Mario Kart styluses this year. I have several of them that I will be putting up on ebay shortly.
