You probably saw where Ausie-guy (I think that's who posted the info...) threw up a thread in the tech forum a week or so agowhere he shared some info on where we could buy a chrono for under $100... Next on the list after my new Toad press!
I have the Shooting Chrony F1 and has treated me well over the past few years. It is around $80 and I made my own light kit for $10.
Shooting Chrony F1 Chronograph
The F1 Chronograph measures the speed of bullets and other projectiles from 30 to 7000 fps. It can be mounted on a tripod or placed on a table and runs on one 9 volt battery (not included) for up to 48 hours of continuous use. The F1 Chronograph features a large display that shows numbered shot velocities. Includes a jack for use with an optional Chrony Ballistic Printer (sold separately). Covered under a 3 year limited factory warranty.
