Alternative Focuser for the William Optics Ultra-Cat-108?

Hi all;

What is the best focuser you have found for the U-C 108?

I have used both the PrimaLuceLab SESTO SENSO 2 which I found slipped and the the ZWO EAF, (older model). I am not happy with the amount of backfocus I have to work into the Hocus Focus formula as well as the lack of repeatability. If 3822 gets me 1.67 HFR, I would expect, a second run within a few minutes would be in the ball part but that is not the case with these focusers.

I am looking at the ZWO EAF Pro, (just came out), attached to the U-C using the belt based system provided by the William Optics EAF Mounting Bracket.

This gets rid of that adapter that connects the two shafts, (EAF to WO).

Can anyone provide some feedback on their best focuser experience and what they are using and their experience with the belt based mounting bracket if your using it?

Thanks in advance.

Bob
