So I was hoping to upgrade to the 1.5hp pm30mv motor on my g0704, but it looks like the pm30mv is not long for the world, and the motor is unavailable. Here is an email I received from machinetoolonline.com

We are not ordering from that factory any longer, we can get replacement parts for mills already sold with serial numbers, but can no longer get extra parts they will not supply them. We are stopping that line of machines for right now.
Does anyone else have a source for the motor?
