I have a potential buyer for my DoA Hori Stick, however I have no idea what to price it.

According to him, he missed one for 50 bucks, and wasn't expecting to get mine for "THAT cheap". I've checked on eBay, and the most recent one ended for $65 + $12 shipping, however there have been three others that ended recently that went for $99+. Also, on Amazon, they're going for $129+ (Which IMO is ridiculous, but if I can get that much, I would greatly appreciate it, being a poor college student).

Anyone have a rough idea of what I should price it? I was thinking 75+shipping, but I don't know if that seems to low or not.
