Joe,
IMO, the inexpensive Chinese spindles with HY VFDs are the way to go. Over time, they've proven to be pretty reliable and cost a fraction of the "name brands." I have no complaints with mine, although I wish I had gone larger than 2.2 KW. I would prefer Made in America, but the pickings seem pretty slim. As a practical matter, you are probably going to end up deciding on which foreign made spindle is for you. I wish I could indulge may preferences, but like many, I cannot justify the expense. Your mileage may be different.
If you want to step up some, you could consider an Hitachi VFD. Folks who have them seem to really like them. I get the impression they put out less noise, although with proper grounding and a line filter, the HYs are fine. I had to add a filter to mine. The cost was around $25 for a good one.
