Re: Cheap 1500W Chinese spindle, experiences?
I have to chime in about the hunyang invertors. I have installed 3 invertors in the past 5 years and they all are running great. I fact I bought a hitachi for school and I think I prefer the hunyang better. The hitatchi has more features and a knob for speed but the huanyang doesn't have a whining fan and just worked and kept working. We finally replaced it to have a modbus controlled invertor. Which I still have been not able to configure.
