A guy at work gave me an A500 with a cardboard box and a shopping bag full of games etc for free. The A500 works perfectly, but most of the disks are no good.
At a car boot sale I saw an A1200 and just out of curiosity asked how much it was. The woman selling it said 'Oh, it's only a keyboard - £4'. I already have a towered A1200 so didn't bother - but now I think I missed an opportunity to get a spare :-)
