Sorry I forgot to mention, eBay will probably be ill-suited for my situation. To be honest, I'm young enough that I don't have a credit card so I have to use my mother's, but not only is my mother skeptical of eBay, but also the fact that on eBay, all the products have almost double the shipping as the price of the product itself.
I also forgot to mention, I'll be doing a lot of rhythm games (stepmania, etc.) on it, if that changes anything.
