Actually, you are safer when dealing on ebay, I think. That's the main reason I bid on NGF stuff. And that his feedback was decent as well. Ebay insures every auction. If you get ripped off, then you can get most of the money back, I think-upto $250??? But the process may take a while.
It's your call. I won their (Ray's) auction and the transaction for the most part was good, in my opinion. My item was as advertised, brand new, w/ fast delivery. If you want to take a chance, like I did, then go ahead.
No offense, but there are so much people still wanting games from Neo-geo freak, and asking if it's ok? All they have to do is check this forum and others. I think people should go w/ this mind set. Be prepared. Prepare that something is going to go wrong. And if it still sounds good (the benefits outweighs the negatives) Like I did, then go for it. Of course it's not fair. The seller has the responsibilty to make his portion of transaction legit, but it appears that this is not happening on majority. So, the seller has to watch out for himself.
