Only problem with DC, by the time you buy a decent manifold, buy the better temp clamp, you've spent more than you might pay for another GOOD brand of RSA.
Plus the Testo and SMAN have more useful functions than the DC
An AK-900 with the Dc manifold included is about 3 bills.
There is no factual basis for this criticism of DC.
