There was a PSA for crazy cheap Reverbs a while back, if one of those would fit I’d go for that.
I have a Reverb on my main bike and a Plummet on my hardtail. When it’s working properly the Reverb is to my mind pretty much perfect – it’s slick, it’s quick, it’s just really nice to use. I also like the remote, run under the bars. But at some point it will almost certainly break (I’ve had a few that have) which is a pain, especially if it does it out of warranty.
The Plummet I’ve only had a few months, but seems pretty good. It’s MUCH more agricultural feeling than the Reverb and the remote isn’t as nice but it seems reliable. It’s VERY sensitive to cable tension, once you get that spot on it seems to run fine.
