Looking for:A cheap GB micro?

[Rummy]

Does anyone by any chance know where I might find one, other than the eBay? By cheap I'm thinking =<£30 ideally. Not too bothered about condition etc, only planning on using it as a cheap alternative to a decent car stereo with my mp3 playing M3.

 

EDIT:Nevermind now, I managed to just bag one off eBay for £17 inc. postage, score!
