I had a PC800 for a couple years, actually bought it for the wife as her first bike. I was riding ST1100's at the time. I did a couple really long trips with it, 800+ mile days no problem. Things are pretty bulletproof and low maintenance, and they're holding their value well.
Hydraulic lifters a big plus, no valve checks. Good low-end grunt, nice low center of gravity. Tipover wings prevent most plastic damage in low-speed crashes. Ladies love the biiiigggg trunk.
If you buy one, be aware the stators need replacing usually at between 50-70K miles or so, but it's easy to do and fairly cheap. Put a datel meter on it to monitor voltage.
We ran heated grips and an electric vest on it at the same time with no problems, but aux lighting in addition to those would no doubt drive the alternator into overload.
Nice bike, good dependable, fun. I miss it.
