Both Paul and IRD make mounts to put the shifters on the bars. IRD also makes a stem shifter mount. The advantage is you can use whatever shifter you choose-

That's just the best of two worlds right there. Silk plus convenience.

There's also the Sachs/Huret ratcheting shifters- those are fantastic- kind of like the Power Shifters, but with a more pillow-y clutch.
I almost feel dirty.
