I bought two brand new 3-ph motors on ebay for $30 ea. That is now my
upper limit. I have converted my lathe and mill to (cheap ebay) VFDs.
Next is my Drill press and bandsaw.

BTW I also have a nearly new single phase motor to dump (1.5HP from my
Grizzly mill). It's Taiwanese. I figure the best value I can get for
it is to take to the local metal/junk dealer and just give it to him.
Maybe he'll give me better deals on scrap aluminum.
