Specifically I bought the MicroSHIFT (that's what's printed on the brifters) brifters and rear deraileur. I have a compact FSA system with the FSA front derailleur. As far as installation is concerned, just follow the directions - nothing fancy. Adjustment, same deal - no surprises. The big surprise is that you can buy a brifter that even works at all for the price I paid ($119/pr). Nashbar claims MSRP at $199, but I've never seen them at full price. The rear derailleur was $29 ($59 MSRP). One thing I did do was replace the incredibly crappy pulleys with Shimano ones. Performance pulleys (11T sealed bearing) would be first choice and I'll make that change later.
Shifting is Campy-style, but without the refinement. There are large and small paddles used separately for up and down shifts and the brake lever is old-school and isn't involved with the shifting. The paddles are plastic and the overall appearance is unexceptional, without looking too cheap. With the exception of the 34-->50 front, shifting is precise and quick if somewhat noisy on occasion (clack!) Going from the small to large ring on a compact is never pretty, but this is the only shift I'd rather have my old (9s) Ultegra for. The effort is high and the response somewhat slow and occasionally a second push is necessary. Trimming works, but I seldom use it since I'm set up for racing.
Under racing conditions it's never let me down, but I haven't had to upshift the front under pressure. When you think about it, that doesn't come up all that often in a race when a 50x21 combination is easily obtainable. I'm on the big ring a lot, with the compact you'll find people do that. Unfortunately, there's no way to say anything about durability or reliability at this point. I have to say I like the Campy shifting better than Shimano. It's nice to have a brake lever that doesn't move sideways, speaking as an old-timer I never gotten used to that.
Even though the shifting is Campy-style the appearance is more Shimano-esque. The brake cables are hidden, but not the shifting cables. The pull ratio is 2:1 (Shimano) so the brifters should work. I don't know if Campy is different, but something deep inside tells me that Campy buyers won't be interested.
