I'm embarking on a 2x72 belt grinder build and one of my goals was to keep the cost down. Having said that I see the benefit of having variable speed depending on various grinding/polishing tasks, etc.
I have 240V power available and my initial plan was a 2HP 1PH 3600RPM motor. Plug up and done. Curiosity got the best of me and I started to look around at 3PH motors and I realized they are no more expensive and even cheaper in some cases, but of course require a VFD for both phase conversion and to obtain the coveted variable speed.
Should I be nervous about a $79 VFD like this one on eBay?

I realize I now have some expense in enclosures, switches and potentiometer. As well as the challenge of deciphering a Chinglish manual. But aside from that should I worry about any safety concerns or damaging my motor.
Any thoughts or experiences will be appreciated!
