If the listing doesn't say who the manufacturer is, The first thing you need to do is contact the seller directly. Ask them point blank "is this from the manufacturer or Is this a cd you made yourself.", if the answer is "this is a compilation, or a very well made copy, or any other answer other than "this is a sealed disc from the manufacturer" RUN very fast. Why spend 100's of dollars on copies when you don't have to? Check feedback!!! If there is more than one feedback saying this is a bootleg or copied cd RUN very fast. Another tip off is shipping Higher than $5.00 with a very low starting price. I have been Buying on ebay for a long time and have purchased these fakes myself. It sure can upset a body when Ebay won't do a thing about getting your money back on bootleg discs. Nor will paypal. So buyer beware check very carefully before you buy.
