Is there something wrong with the old ones? They're often repairable, or there are lots of good used ones around. If there's a bike co-op nearby, they probably have a few in the salvage bin.

I used a pair of those for over twenty years, many tens of thousands of miles, across the USA twice, and I loved them. They still worked fine when I sold the bike a couple of years ago. They had to be cleaned every few years, and the cable checked often for fraying.
