why don't you just do what several other people have suggested given that you don't need the cash from eBay...

sign up on d2jsp.org, trade your items/account for FG (forum gold), and use the FG to get D2 Items and even full accounts (characters lvled but stat/skill points remaining). this seems the most logical to me given that you want to trade WoW for D2 .... as you post says.

be careful on jsp. typically, the user who has a higher post count will expect the Items or FG first. a way around getting screwed is to request a mediator/moderator. you can do this by clicking the link in your post (top right) or PMing a mediator through the mediator availability list at the top of all the trading forums. if you're going to do full accounts, you may also want to get vouches from people (though they really don't mean that much). i'd stick to mediators until you have 500+ posts.

good luck man, and like i said, i think that's the best route, just remember to be careful to not get scammed.
