Seems it's one thing after another with my vans the last few days. The
van I need to tune has a dead tach. I have an old Sears engine analyzer
in which the tach has always worked - but today it decided to die on me.
So - I need a cheap inductive tach just for that one purpose - setting
the rpm for whatever operation I'm doing. Anyone have any suggestions?
Cheap is the operative word here. Functional is important too.

Thanks.
