Around $100 unless you want the solar powered style which is a little more. After 5-6 years you will have to change the battery on the regular tach which use a watch style flat battery. Im mentioning this because some of the tach's are throw away style where you cant change the battery.

These folks make the branded models for Echo, Stihl and others.
