I had wondered about the Yaesu rotator.  I currently have a PST-61 to go 
back on the 45G and have a modified Ham IV for the LM470, but a nearby 
kam has the Orion in a 90' crank-up. If the Orion will fit the LM470, I 
may go that way.  I'm working on the rerod cage for the base at 
present.  I have to get help to lift any of the heavy stuff, or to hold 
things in place so it's kinda slow going.
