I have a Starlight Feathertouch on my 9.25 and it's great. Silky smooth and very reliable.
It's an entirely different experience to using the rubber stock focuser which comes as standard.
The Feathertouch allows for very precise and stable focusing. Even the degree of shift when imaging is reduced.
Anyone buying one of these for an SCT will not regret it
