Based on going conservative going rates, I'd estimate my package to be worth about $400. Ebay says that yours is worth about $240. I've gotta do special shipping, while you don't. You have to go to a FFL to recieve, I don't.
I guess $160 would be fair.
I'm still holding out for an other offer on a trade, however. An Ipod isn't much of a priority to me. Besides, I don't know if I'll be able to ship until Saturday anyway.
