I have a Pact (i.e. the RCBS is a green Pact) from about 4-5 years ago. Works well, but a tad slow. Need to get off my duff and box it up and send it to the factory for the upgrade to the newer electronics in the dispenser that make it faster/more accurate.
One thing I keep an eye on w/ mine is that w/ larger charges of extruded powders (for me, 40+gr of Varget, H4350, H4831, IMR4064, etc. such as for a .308 or bigger) it tends to over-throw about 0.2gr... so I just set the desired target weight 0.2-0.3 low, and use the 'Dispense' button to trickle up the occasional one that actually comes out right /ubbthreads/images/graemlins/wink.gif The newer electronics and guts are supposed help w/ or take care of that, according to the factory tech on the phone.
HTH,
Monte
