I understand your frustration, did they give you a reason why they suspended your account?
Recently, ebays actions have been rather knee jerk, than anything, with limiting and suspending accounts for little or no reason.
Personally, I don't know of any other auction site that has the same traffic, however have you tried Craigslist, it works for me selling info products and physical goods too.
Craigslist is huge, give it a try??
