I can relate to most all of the comments above, but I'd say #1 for me is the advent of the TPGs, specifically the non-linear price differences for high (8, 9, 10) grade cards. Paying 10X (or more) for one card over another because of some small issue that cannot be seen with the naked eye has priced me out of owning high grade vintage cards. It has made that end of the market very competitive.
