Andrews (Lee sure can talk if the shop is quiet) have GSO focusers. I just put a two speed one on my ST80.
I was thinking of getting a GSO focuser for my C8 but it doesn't seem to have an SCT thread option on the eyepiece side.
If I put my focal reducers (6.3 or 3.3) on the front of the focuser I think I'd wind up with too much separation between the f/r and the CCD.
I think that means I need a JMI - probably an EV-1cm.
