I bought my system from ebay. If you want to make sure this guy is legit this is what i suggest. Contact him by email and ask to setup a phone conversation, and get HIS number. Second while on the phone ask for the service tag on the system, so you can look it up on dells website. Also look at their feedback, make sure they are a reputable seller, with feedback from OTHER reputable buyers/sellers. And never ever ver ever ever ever ever send a money order, or direct wire transfer to a bank account. And never mess with ANYBODY outside the U.S. 9/10 times if the system is out of the country its a SCAM. Take these precautions and you can get a great system @ a bargain my system with shipping was only $1525 w/tax and warranty. Ebay is a great community you just have to be VERY careful. And if the deal seems too good to be true, then it is.
