It looks like a good price IF AND ONLY IF the dealer is legit and the drive is in fact factory refurbished.
The problem is, you have no way of knowing if that is true.
Any purchase of computer hardware from an unknown dealer on ebay involves a leap of faith. You pays your money and you takes your chances.
I find it peculiar that the Internet is littered with similar offers trying to sell that particular drive by many different second and third tier sellers. Make of that what you will.
It is further peculiar that I don't see that particular drive offered for sale at a well-known legitimate retailer.
Would I take a chance on it? No.
