This is idle curiosity at this point because I just bought a used festool CT22. I was trying to work up the nerve to buy a Fein III when I saw the Festool at a great price.
But for anyone who has seen both... Are they roughly the same power? Festool claim slightly higher CFM, but slightly lower static pressure. The festool seems to be a bit more powerful then my old Hoover GUV, despite the Hover having higher amperage. How about noise? I am very pleased with how quiet the Festool is; can the Fein really be much quieter as claimed? The Festool is way way quieter than the Hoover, eventhough the Hoover is way way quieter than my old old Shopvac.
I have googled, and there isn't anything meaningful out there.
