So.. I'm looking at Borg Focusers thanks to Kev!

Has anyone had experience of the larger variants of these? I want to fit this behind the Pentax's rack+pinion single speed focuser which is rock solid but missing the fine adjustment.

It needs to cope with OAG+FW+383L+16IC+Powermate without flexing and preferably has locking nuts to prevent movement.

Anything I need to consider?
