I tend to agree. The Judd's are certainly a bit neater than the ones that I have personally obtained for my collection but a lot of the other cards the signatures are no better than what they give anyone else. I don't believe adding a signature to a basic card makes that card suddenly worth $20, $30, $40.00, or even higher. Maybe if that person was deceased or they point blank refused to sign but otherwise there could be 100's of the same card floating around. That is certainly the case with the NRL cards that appear on this site. Each to their own I guess if someone is willing to pay that much, but with mine I know they are original and a bit more significant in that I obtained it myself.
Getting away from the issue it is amazing how many forgeries are floating around on Ebay and when you report it nothing is done about it. They get their their Fees and someone gets ripped off.
