Anything around a £1000 would be a good buy. Just remember that you could require a fair few parts to get it running such as new battery, sevicing of the brakes or possible new ones, probbly new tyres, definatly a sevice before attempting to start it, and mybe the cluch could have seized. There are quite a few things that can seize up and stop working after a short period of time if its not stored correctly so work it into your price.
