I'm thinking about getting a generic all-purpose VGA adapter for my classic systems (Sega/CD, SNES, 3DO, NES). I found one at Gamestop for 50 clams. Is it worth getting one?? I've hear generally negative comments on cheapo adapters, but I'm not looking for uber-XRGB quality here. I mean, the sources are composite and some S-Video, tops. Any suggestions? Thanks.
