I have a DPS 2 with the speed upgrade making it a DPS 3, I really like it. The differences between the Lyman and the RCBS is that the Lyman is one unit, the RCBS is a separate scale and dispenser. The RCBS is rated for 300 gr larger loads and costs about $100 more. I primarily use mine to throw charges about 2/10's of a gr light and then trickle up on a separate scale. Many people just set the charge weight and rip. I don't think you can go wrong with either one. If I had to buy again I'd buy the Lyman due to the cost and size (being smaller) than the RCBS.
