I have lots of bikes, but all of the ones I ride regularly have brifters of some sort (Campy, Shimano, SRAM). One exception is a '94 Bridgestone RB-T that's in the commuting rotation and uses 7-speed indexed bar-ends. I used to mostly use bar-end shifters on most of my bikes, whether friction or index, but once I went Campy Ergo, there was no turning back. My oldest bikes set up that way are a '71 Raleigh International and a '73 Motobecane Grand Record, but most of the others are relatively recent.
