I have used several of the KB Electronic VFDs, there are decent, but are quite limited as to features and lack the ability to be programmed (they have a few pots for adjustment of functions). I ended up replacing all of them because of performance issues. I would recommend KBVF series VFDs for very basic use, such as a saws, but for a mill or lathe I believe you would be better off with a sensorless vector VFD (Automation, Teco, Hitachi...). The price difference is relatively small and you get a lot more functionality. If you went with a 1HP 3 phase motor (230V), you could run it off a 120V single phase input VFD that would output 230V 3 phase. This gives you flexibility if you do not have 240V line.
