If you can lay hands on a 1973-ish Raleigh International. I can definitely recommend it. They are a great mix of comfort, versatility and performance, with a bit of chrome flash thrown in.
Grand Sports and Competitions are a bit more common, and are also versatile and have geometries that are pretty close to the International.
This said, I have a 1972 Fuji Finest that in many ways emulates the look of the PX-10. I've never ridden a PX-10, but if it is close in feel to the Fuji, it would not disappoint.
