I like having a tach but for $20 you can get a portable laser-tach from amazon. Make sure that the idle is always less than 1000 rpm. Only shift with the throttle all the way down. Then on the top end of the RPM range try to run full throttle to prevent coking up the exhaust elbow. As the bottom gets dirtier I can tell because my Kts to RPM ratio starts dropping. Those are the only useful reasons to have a tach. Only one is a necessity - shift while less than 1k rpm.
I replaced the gage on my tach for $100. That quite a bit more expensive than the $20 laser-tach.
