My 2 cents - VFDs are awesome. I am using 120VAC 1-Phase to run a 208Vac 3-Phase motor with 1 hp.
I also spent the extra 30 min it takes to adjust the low end torque so that the motor keeps spinning when loaded up.
I can spin the part at something around 20rpm and it won't stop moving. That's the biggest benefit for gunsmithing. You can take your rough chamber cuts at nice low speed so you never over-cut. Then spin it up super fast for the last 0.010" to keep the final finish good.
My model is a Teco brand, which is really easy to use. However, if you have the money, the really nice ones have presets for different situations. I got to use one that was custom fit to a Hardinge industrial lathe and it was a joy.
