I don't have a whole lot of actual collector goals, but as usual, I'm kicking myself for not getting something when I originally wanted to--ColecoVisions are skyrocketing in prices right now, and two years ago, they were still hovering around $30 instead of $100.
Two of the few goals I have, however, are to have complete collections for Virtual Boy and Microvision, just because. I'm over halfway there for Microvision.
