Agreed. Being able to buy rare or crazy hard to find things on ebay is one of my favorite passtimes. it's definetly great for moped related things. the good far outweighs the bad, and they haven't "partnered" too annoyly with other retail companies yet -- which i thank them for.
on top of that, it's on of the few really unique internet ideas. it wouldn't be possible without the network, and i'm always a sucker for that.
