I had the Lyman. (Lyman 1200 DPS 3 Digital Powder Scale and Dispenser System 110 Volt) It went back for repairs (motherboard, power switch, and keypad) three times in the first year. It was only close to accurate when left turned on, and then it would overheat and shut itself off. I ended up sending it back a fourth time, and to their credit, Lyman refunded the entire purchase price, a year later.
I would get the RCBS, which is what I have now. (RCBS ChargeMaster 1500 Powder Scale and Dispenser Combo 110 Volt) I've had it a couple mouths with no problems, except it throws about 1.0-1.2gr light on large charges, which is fine since I trickle the last few 10ths myself anyway. I can set it .08-1.0 heavy and it is very close.
I have no experience with the Pact model.
