A lot of people use them. They just about throw 'em in for free with a spindle on eBay.
I would MUCH rather spend $300 on a high-performance, high-quality, well-specified Hitachi VFD. I need to be able to trust my components. Look up Hitachi WJ200. WJ200 is a product LINE though, there are different KW and power input types within that so don't just order "a WJ200". The suffixes are critical.
