Rest assured, I understood and actually share your feelings to a great extent.
I haven't even seen the exact item to which you refer and have no idea who the seller may be. Only speaking in general terms for such a situation where the signing fees are this high to begin with. I'd likely be asking a similar amount if I was trying to sell one. Thankfully for us all, there are so many more historically interesting autographs to enjoy without having to resort solely to illegible scribbles that were signed for the express purpose of being a valuable commodity.
