A loose pce in Japan costs 1,000yen max. Only spend more if you want one minty or boxed.
Checked through my mail,, and this is what my friend got for me while he was in Tokyo:
PC Engine For 4500 yen and Core Grafx II for 5000 yen.
Also Bomberman 94 840 yen and Axelay 1500 yen
And I think that was some of the cheaper ones.
Ah, here's why I thought it was 3000, this is the first list he got me:
pc-fx (large ish tower) 6 - 10000
cd(big one) 5 - 6000 yen
duo 9 - 10000 yen
duo r 10000 yen
duo rx 12000 yen
core graphic II 6-7000 yen
core graphic 3000 yen
