I have had a number of lathes over the years, and I install a QCTP on every one i get. I have only had one Aloris, and it was used when I got it, so it may have been worn. But it did not look it. At any rate, I have had a Phase II, a couple of CDCOs, and maybe a few others. They all worked fine. The only one that gave me any minor problems was the Aloris, in that I never could get the handle to where it would lock out of the way. It always hung over the work no matter what I did.
CDCO just went up on their generic QCTP kits, so for the same money I'm going to buy a couple of tools4cheap units. Nice guy, and he appears to have an eye for quality, and a low tolerance for...low tolerances.
ETA - just checked both sites. T4C is lower on the piston type, and higher on the wedge type. On average it's a wash. I don't know who ships cheaper.
