Roland,
There out there, my friend. For about 4-6 grand, you can pick up a fairly reliable and cosmetically very decent example, and for anything more than that figure, you should be able to buy a very pristine one. I wouldn't, if I were you, even consider one for less than that, as you'd be putting a lot of your money into it, in order to make it something you could appreciate and ride.
I suggest you look at at least half a dozen before you decide on a particular purchase.
There's usually a few in the "Cycle Trader" magazine(in the back) located in our local area(SO.CAL) and I'd pick up Walnecks's Classic Cycle magazine in order to get an idea of the price ranges. E-bay is also a good source, but with both Walneck's(which is national) and E-bay(the same, of course), you'd be looking at bikes that you really couldn't see personally, and I'd shy away from purchasing an older bike, especially, without first being able to ride or at least examine it closely.
