www.animeniacs.com (Very nice people, great to deal with, have bought from on many occasions)
www.animekrazy.com (Have dealt with them as well, no problems at all)
www.pokerindustries (Have never dealt with these guys, but they have a ton of stuff, including live action, but read before you buy because a lot of their stuff is region encoded for those of you who don't have region free players)
www.chibitokyo.com (They don't carry anything Hong Kong or region free, but they do carry music for cheap as well as a lot of toys, they're based out of Atlanta and they're really nice people, great to buy from)
www.importanime.com (Have never bought from them, you have to sign up as a member to buy from them, but the really neat thing is they are a reference site with reviews from fans on the subtitles, transfer quality, audio, stry, and show in general form the diferent importers. This site if used properly can save you from buying a poorly done copy)
