Good luck Andy, hope you find a good one, but take care, they can outdo a lot of 900s on accelleration & bendy terrain, especially in the 7000-10000rpm band. I had one back in the mid 80s, black & red, fabulous. I also know someone who used to race them & he bears me out on my statement about the 900s, so please take it steady for a while, they're not for the inexperienced, although you should find them, if original spec. & well maintained, very well balanced & predictable.
