I was wondering where everyone bought their NTSC/Jap games from on various formats.
Recommendations for value/reliability etc..

US: VG+ / Tronix

Japan: Play-asia / yesasia

2nd hand: here

NCSX are reliable for both US and Asian games too, but they're rather pricey (especially compared to VG+). They may be a reasonable alternative to PlayAsia though, especially stuff that PlayAsia won't ship to the EU.

genkivideogames deserve a mention in here. Always have got my stuff the day after I've ordered without fail.

I'd second Genki. I have bought a couple of games from them through their Ebay store, and their service is superb.
