I've had my Lyman DPS II, which I upgraded to version III, for about three years, it's been on the last 2yrs at the recommendation of Lyman to eliminate the warm up time, works just fine. If I were buying one now, I'd probably go with the RCBS, there isn't as much difference in the cost now, I got mine for under $200 shipped, the RCBS was $60-$80 more then. Both are made in China if that makes any difference to anyone, the Pact is the only one made in the US.
