Why is it that higher quality multiple bat display cases (which are basically a large glass picture frame-$40, hinged to 4" deep rectangular wood framed tray-$60) are always in the $350-$600+ range? I prefer to display bats horizontally in a glass display case and to make one is fun. It usually ran me under $100 to make but I can't make them anymore. Looking on line for additional ones I find all quality cases to be way out of reach. I know that a good display enhances an item, but not at a 400% average mark-up.
