What TACH do you like? Digital or Analog?

[PuttPutt]

I am wanting to get a tach for all the times you need one to tune on your bike. I have one built into a multimeter that has RPM and a lead you clip on a plug wire. Problem is, the damn numbers are all over the place. It reads RPMs but one moment you think you are set at 1050 then you are at 850, 975,1300,1100, then it bounces to 800....I mean I am totally tuning and syncing by ear, cause who knows...drives me crazy! So I am in search of a tach like the one in my service manual...I have a 96 Royal Star XVZ13A. So please tell me...do all digital tachs bounce numbers around or is it just the format of the multimeter. I have read that people fuss about buying a digital and it cant notice when you adjust something or is to slow in putting a read out. All thoughts and info on a good one would be great! Thanks all!
