Here you go Rob .
I got this from Andrews Communications about 3 years ago for the total price of $49 , I think they have sold out now and as you can see they were off an 80mm f480 refractor of some sort , its been an awesome focuser that has never needed tuning and as this is my wife's scope it gets lots of use .
I machined up a 1mm thick adaptor for it to fit the 90mm tube , see photos .
The Esprit focuser I got for my iStar was in need of urgent surgery as it was really terrible in use and I had to completely strip it , clean it and carefully lubed and adjust it yep these are super fiddly to get right ( that's why the origonal owner had , had enough ! ) but once sorted , like you say these are very , very good .
This one had tiny bits of swarf in the fine focus ball race
small but plenty enough to not work well .
