Just had a pair of Campag chrous ergopower levers installed on my touring bike. Picked them up for 90euro(90usd) on ebay. OK, they are a little worn, but work fine.
What an experience! I used shimano bar end in both friction & index mode previously. The campag system is far nicer IMO. Very positive, smooth shifting with hardly a sound. Had a couple of new hoods put on, and they are damn conmfortable. Glad I took the advice of the bike newsgroups.
