HM, Translogic, Dynojet - all good quality.
I've got the translogic quickshifter and can highly recommend them. They aren't cheap though - about $750.
Mines got the "on the fly" dial for adjusting interupt settings while riding, and is active from 3500rpm so it can
be used even if just cruising around. Programming is done through it's own ecu and is very easy to setup and adjust.
