Too bad these import game soundtrack CD's come at premium prices. There are ahem, other places to get them, but that means you're supporting less than legit companies from Korea or Hong Kong.
Yeah, unfortunately importing is the only way to get a lot of soundtracks from a lot of anime and Japanese made video games. Sometimes I think that it's worth it. I've imported several soundtracks to games and anime (mostly from Miyazaki movies because Joe Hisaishi is amazing...). It can be costly at times, where normally a cd would cost 15-20 bucks, importing it cost 35-40 bucks. But if it's truly a good soundtrack, I feel that it's worth it.
