As a collector i prefer to have the original Japanese release. And if possible, the first pressing as well. Still, when i'm in Bangkok, i often can't resist buying Thai, Taiwan or HK pressings.
I have to admit, this hobby has gotten a bit too expensive for me to keep up.
If you're looking for a new market though, try selling second hand cd's, just like e-bookoff does. Except they don't ship overseas (yet), but if you could do that, i'm sure i'd be interested.
