I've got a line on an RF-30 at what seems like a decent price. Went and
checked it out the other day, and I've been doing some research on that
line of machine from various vendors.

One thing I ran across from a couple different sources is that the motor
causes vibration that results in only fair finish quality for some types
of cuts. ...

My testing of one new RF-31 from MSC suggested that 0.1mm or perhaps 0.05mm
accuracy was the best it could deliver for multiple reasons, and correcting
the easiest of them wouldn't help much. I brought a few demanding jobs home
for the better accuracy and surface finish of my 50+ year old Clausing.
