It's pretty hard to resell sticks now and days. After SF4, it's gotten soooo much easier to get a stick. You got Madcatz, MLG, Razor, Hori, and random as koreans/chinese stuff. And they've all got sanwa'ed entry-level sticks going for around 150$, and selling to the US. Anyone who wants a stick probably already has a stick.
maybe if you threw in free stick art or something. pretty cheap and easy to do yourself. maybe. If the eightarc has some sort of plastic cover or something, then it's easy. If it's like the Madcatz sticks where you gotta get your own, then it'll cut in to your profits.
