Sure, Spiker and the like are always tough to come across, but is there anything else (game-wise) that eluded you for way too long, or still does?
For me (again aside from the later INTV releases that seem to run away from me all the time), it's frickin' Turbo and the Hong Kong Shark Shark. I can't, for the life of me, find a decently in shape copy of either.
