Most of my stuff has come from eBay. Without eBay my PC Engine collection wouldnt exist!
There was a time when getting NES stuff was as simple as walking to Funcoland, but ever since Gamestop swallowed them, I cant find anything 8 bit at all! I went to three Gamestops here in NYC, two of which were converted Funco's, and two of em carried NO cart stuff other than N64 and GBA. One other had Genny and SNES, but no 8 bit stuff. Truly was sad. End of an era...
