There are a few in the Dallas area, but most are just overpriced. There is a palce called FX Game Exchange, A few Game Xchanges, a few Console Game Xchanges, a place called game chop (currently liquidating retro stuff for all modern, which leads to cheap finds, like my .99 Jag and .01 Atari 7800), and of course Movie Trading Company, which is horribly overpriced. There used to be a place called 3D Games, but they always wanted outrageous prices for TG16 stuff ($150 for Soldier blade loose, etc.), but I did find good NES deals there (Zombie Nation CIB for $15). All in all, still usually best to stumble around flea markets hoping to cross someone that has TG16 stuff, which of course never happens :\
