I put a Moonlite on my C8 for almost exactly the same reasons. I rough focus with a Celestron Motofocus and fine focus with the Moolite.
The trick is to make the final focusing on the mirror turning the knob in a clockwise direction so the mirror is being pushed rather than pulled.
Then fine focus with the crayford.
It holds my DSLR or QHY8 without blinking an eyelid. The photos on Moonlite's site have it carrying a filter wheel and much bigger CCD than mine.
Also it can mount a focal reducer on the front of the drawtube so it is at a constant distance from the CCD.
