I had one of their scales a number of years ago when digital scales were a newish thing for reloaders, and it was very unstable. I was able to talk to Pact by phone & subsequently returned it for repair. When it came back (pretty quickly), it was a much improved unit. Hopefully their customer service is still as good for you.
As far as chronographs go, I can't say enough good things about my Oehler 35P, though they aren't available new anymore. However, Ken Oehler still provides wonderful support. I just got a new printer head from him a couple of weeks ago. If you are a little patient (I know that's asking a lot of most of us), you can get a good used Oehler. I have seen several on 6mmBR.com in the past year or so.
And BTW, Ken Oehler would still like to find someone to take over his business & put the product back on the market. So, if there are any enterprising electronics types out there, you might give him a call.
