I'd go $150ish posted for YOTG Soundwave. Being a left field colour scheme, it didnt set the place on fire when it was released.
As for the MP02, $250 isn't *too* bad considering if you were to go the Takara route you'd need to buy Soundwave then fork out extra for the 2 cassette packs which do add up... but that broken finger? That's the sort of stuff that would keep me up at night.
