White Light Scanning

We are looking into purchasing a new White Light scanner for our use here (possibly for a CMM replacement) and I thought Id get some opinions from any potential users (brands or prefered software) out there in the PCDMIS user collective.

The white light scanner wont be running PCDMIS of course.

I have 8 years using WLS (whitelight scanner) as well as CMM, WLS is pretty accurate but has issues with noise ( light reflection back to the cameras) and the paint coating you need to put on the parts.
if you can collect as little noise possible without coating then
yes is very accurate but it will not replace CMMs.
here we scan very small blades just to generate a preliminary CAD model very quick, then we process the same blade on the CMM with the CAD from WLS to refine measurements, then we correct CAD with CMM data.
