i haven't heard of anything like a mod chipped ps3. All titles are region free and available universally, unlike xbox360. Wheres the need to mod a ps3 then?? You can get an import from US or buy a 40gb ps3 from sony india, its all the same
And piracy - yes bluray games/movies can be ripped, but i would recommend we not talk about pirated content on this forum.
All PS3 games cost almost the same everywhere in the world, yes bluray movies are cheaper in US
