(Note to Steve: one obvious problem with using imagemaps is maintaining consistancy to the bloody end..would it work to put traditional links to mfgs. on the pages highlighting the cards. Might let you include additonal mfg info if necessary without making this somewhat cumbersome page too different from the rest..or am I obsessed with presentation? I can add new tags in minutes..)
PS: Is this where you also offer to add support for new cards in exchange for free samples?
