There are not many companies making timing lights, anymore. The only down side to dial back timing lights like that is that they don't like multi strike ignitions. They can throw multiple flashes making it all but impossible to set timing on multi strikes. The tach is a nice feature.

I have 4 or 5 timing lights in the shop now. We use them more for diagnosing problems than we do to time. Not many people use them anymore, so they pop up ever so often on Craigslist.

This summer, I bought a nice Craftsman inductive light still in the case for $20.
