Auto Dynamic pumping

Seen a few threads on auto dynamic pumping, but seems the actual pumps are few and hard to come by ? I only know of Q7 Etc few others which are pretty old now ? Are there know suppliers or options suggested ? I have started my kit with LAPump cylinders and Gauge but keen on the dynamic aspect of possible.

The only one I know of that’s still available is the CTC DP4000
The Q7 hasn’t been on sale for years and Vacutech have ceased trading recently.

Hey Guys, I had the CTC DP4000 and honestly it needs some serious updating. It very complicated and it needs a computer and USB & CD drive to adjust it. I had it for 4 months and sold it. For what’s available today go with the CTC 2000. But over all the pumps that have been available on the market the Pulsar is by far the best that has ever been offered. So sad its off the market, I only hope someone buys the rights to it and gets it back on the market.
