My VC200L has the stock R&P focuser but I have replaced one wheel with a simple skywather power focuser

It bolts on with no modification needed.
I have a heavy ST10XME with AO unit and filterwheel on the back of the scope and almost never need to change the focus. I focus with a Bahtinov mask on the V filter using the motor and then lock the focuser. It will stay like that for weeks before needing to be changed. I check it each night with the mask but rarely change it.
You don't need a 2 speed focuser as you can perform small enough movements with the hand controller.
