Just wanted to let you know:
Recently, I bought two Suikoden OSTs on ebay (for a REALLY good price). I got them this weekend, and I noticed that they were not official Konami releases, but Taiwanese bootlegs. That wasn't in the description of the auction, and it doesn't bother me much (I need to listen the CDs to check them for quality), but for a collector, this isn't so good.
So this is just a warning to all those looking on ebay for cheap OSTs - there are bootlegs. There are also bootlegs for other games' OSTs (they advertise them on the OBI).
