Sorry for this double post (also in Parts for Sale) but thought it might be of use to someone. Saw this on the Sun website. Seems like a good deal if you need a tach. http://www.sunpro.com/cgi-bin/web_store.cgi?page=cp7918.htm&cart_id=7239685_12744 Anyone running this tach? I'm in the market for one but don't know if I need a 10k RPM tach and 5inch display.
