    Small cheap short Wave/Mp3 player

    Hi all, What i'm after here is something a bit like one of those naff Xmas/B'day cards with a scratchy (but hilarious) audio playback when opened. I would prefer slightly better quality but nothing audiophile! lets say 3 sec audio, single channel, 22khz, battery powered, finer points TBA...

    Philips 32PF5521D/10 Stuck in Standby Sortof
