Crayford - don't expect it to hold much of a camera. Stay with the Tak R&P, adjust it properly, and you have a SUPERB focuser (I have tweaked mine to be as smooth as silk on all my Taks and prior Taks). Add the Tak MEF3 reduction unit, and you get a beautiful 2 speed R&P. Or buy the Feathertouch Micropinion (which reuses the Tak pinion anyway) and you have a 2 speed R&P that is not quite as good as an original (I find FT puts too much backlash on the reduction unit and its a pain to adjust it due to them loctiting it!). I found the standard Tak R&P held a 5kg imaging rig without issue. The crayford...not a chance.
I have had FT's crayford on FS60's, and whilst convenient adapter wise, it would NOT hold weight, and nor would it forward travel even with a slightly heavy eyepiece despite adjustment.
