First MB purchase-advice appreciated

[Lion]

When buying on Ebay to me you have to trust and have faith in the seller and see what his or her feedback has been in past transactions before taking a chance. It's just too easy for a seller to rip you off and do you really want to take that chance? Also they can make mistakes too with out any malicious intent and do you want to be the recipient of their snafu???

2careless is correct though, if you know what you are doing and looking for there are some really good deals to be had on Ebay. But if you are a "Newbie".....do you really want to take a chance and especially on your first purchase!!!
