The Acorn Electron, the cheaper yet most competent little brother of the BBC Micro, is a fantastic, compact, good-looking and downright lovely 8-bit micro, that usually comes with an incredibly affordable price-tag too. Take this Acorn Electron for example. It costs less than 25 pounds, is in full working order and comes with a variety of mostly boxed software, among which you'll find such games as Boxer and Arcadians. The only thing it lacks is an aerial cable, but those are very easy and cheap to grab; you probably have one already. Oh, and the seller does sell worldwide.
