I also use the Oehler Model 35 chronograph. For timers, I'm using the Competition Electronics Club Timer IV. It is bulky but its scoring function makes it nice for automatically and quickly scoring points down from an IDPA target.
All of my stuff is Competition Electronics. Timer: Pocket Pro ; very happy with it. Small size, easy to use.
Chronograph: old Pro TNT. I think that I bought it in 1988. Originally bought it because it is a combo timer/chrono. Too bulky compared to current timers like the Pocket Pro and PACT Club.
Also, I have been very satisfied with the customer service from Competition Electronics.
