I think Campy would be selling more Ergopower if more people learned about Shimergo setups and Hubbub derailleur rearrangments.

These ergopower shifters have just a great feel to them.
My setup is a 9sp ergopower shifters, shimano shifter, on 7sp freewheel. (I'd like to make use of a new campy wheel I got, and upgrade to 8-sp capability; but I think I'll have to make my cassette; I want the old campy 5mm 8sp spacing, but I hear that newer campy wheels use aluminum in the freehub body, so that although the old 8sp cassette pattern will fit, they will tear the freehub; I will will try to get a miche/campy 9-sp cassette, and an 8-sp cassette, and rebuild the 9sp using the 8sp spacers, into a compatible 8-sp compatible with newer wheels like the campy khamsin.)
