Hey Henry - yea, Sapphire complete mint w/spine card, registration card, legit can be had in Japan for about $275 to $450 brand new sealed. I've bought 2 for $275 each used. Re-Sold it the first time (since I played it on a crappy TV, I was not impressed by it at all), but the one I bought recently, I really was blown away since my TV is upgrade and man, Sapphire's effects are ridiculous and it's a great shooter, even though I hate overhead shoot em ups!
Best way to tell fake / non-fake is looking at the inner CD band. IF it doesnt say HGCD, it's a fake!
thanks for the link nat
