Hey CAYUGAD, I have the Pro Chrono by Comeptition Electronics and like it very much. It will do everything you need and adds a whole new dimension to a range session. Price at Midway is less than $100.

Whatever one you get, be sure to make a plexiglass shield for it to use when you shoot sabots. Mine took a sabot to the face - broke the LED display - sent it back to Competition Electronics - $40 repair bill.
