if i were you id think that over. ebay is a good website and all (iv been scamed there before) but i would really think it over and NOT buy it. you never know what can be on it (viruses, spyware, keyloggers, adware, remote access software, malware) ,those are just some of the stuff that can be on it, so instead of risking your computer just buy one from the stores. Its going to be eather savig a couple of bucks and risking your computers life OR buying one from a store...
UP TO YOU!
