I think that's a 1991 model. I've got one of these and can do nothing but praise it. It is one of my heavier bikes but it is also one of the faster ones and despite the heft one of my better climbing machines. It just seems to transmit my meager power to the road better than most bikes. I like mine so much that I kept it over a mint 1987 Waterford built Paramount that had better components. The PDG was just always faster over the same route. I'd get it for the frame alone and then start upgrading parts when you can.
One thing to consider though is as mentioned above, tire clearance. It does have tight tolerances. I cannot run my preferred Conti GP4000s II 700 x 25 tires on it without the front rubbing. A true to size 700 x 25 might fit though.
How mine is configured right now.
