if you're after a vintage one have a look at http://www.devoted2vintage.co.uk/. Some of the stuff on there is horrible, but they do tend to have some good leather jackets on there at good prices, got mine from there and couldn't be happier.
If you know anyone going to USA, ask them to bring you one back. Friend brought mine back for £10 though will be slightly more now as the Dollar is stronger.
