Want to instantly join the ranks of Rockman collector geekdom? Now's your chance. Somebody is selling the complete classic series Mega Man Game Boy Collection on ebay. "Complete" as in everything: boxes, booklets, cartridges. Yeah, this is sheer win.
Such a godly collection won't come cheap mind you,the bidding starts at $600 with the option to "make an offer." If I were you, I'd try for the later but I don't know how low the seller is willing to go.
Best of luck.
