I have a Pact Model 1 XP. Cost is $130 (through Midway) complete with sensors, skyscreens, and all mounting hardware. It has been reliable and repeatable.
Unlike the Chrony products, the electronic computer unit sits on the bench next to you. Only the sensors, skyscreens, and mounting unit are out in front of you.
It will give you velocity for each individual shot and statistics for shot strings such as average velocity, standard deviation, average deviation, velocity extreme spread, etc. But you can't download to another device so you will have to write it down.

Pact now makes a Professional Model for 100 bucks more. It can print out and download to an SD card or a PC. It also calculates power and trajectory data.
