The benefit of the Moonlite draw tube-fitted FR is that it maintains the back focus distance to the imaging sensor no matter what focus adjustments you make. Whether that's of particular use to you is a personal decision.
"M14" = Meade 14" SCT? Is that ACF optics or standard SCT? If ACF, be careful with selecting a suitable FR - although my research is not complete, so far only the Optec Lepus 0.62 Telecompressor and Astro Physics CCDT67 look promising.

Thanks Astro Bot. I had forgotten about JMI and hadn't heard of Baader focusers, so will check them out. The JMI SCT models seem to have only 1/2"of travel. I'm not sure if that's enough, although I guess that the mirror could always be reset to a new position to achieve focus.
Yes - I adopted the term M14 as in C14, and it is an ACF model. I have also read that the Lepus and AP FRs are the go.
thanks, Chris
