I'll admit that it isn't the prettiest looking table out there (partly because I cobbled it together as a starting point for discussion).

Your idea of tiers is an interesting one, and could help make the price guide more simple and intuitive. I'll have to think about how to work out the details, but dividing cards up into tiers based on current demand does sound like a promising idea.
