I have an 8” Wahuda, which was/is somehow related to Cutech. Love it, great machine. The only thing I’d do different is buy the 10” version (or wider, if they offer one)…which they didn’t have when I bought mine. Of note, it’s an offset ‘spiral’  multi-carbide-cutter head, not a true helical cutter, but it works just great and makes changing cutters easier (but a little tedious). 

Wahuda is headquartered in Tennessee, so at least there’s someone in the US to talk to. Highly recommend! Buy as big as you can afford!
