Actually, I've been running 2.4 ghz manually since AO-40, and really haven't had that much trouble.  Just keep spinning the dial.  Also, having an older rig (736r), I don't bother with computer control when on the linear birds.  I do relax under full computer control for FM up through L-band, but there's still something satisfying about manual tuning.
