Yep, the size and positioning of cantilever studs are standardized - you can swap in whatever cantis you like and they will work. There are differences in shapes, angles, pad style, and there are slight differences in the adjustment procedure between the different kinds of cantilevers, but they all use the same studs.
If you want a recommendation for modern, new canti's, I like the Tektro CR720's: they work well, are relatively easy to setup, look good, affordable, and they come with nice pad holders that use standard road pads and are easily adjusted.
