Well you mentioned no moonlites, but the moonlite is a fantastic focuser.
I installed mine a couple of weeks ago.
I had to drill 4 new holes in the tube to fit it, but that wasn't nearly as scary as it first seems. Measure twice, drill once.. and the template and instructions provided by DBA Astronomy really made the job easy and not stressful at all.
The fine focus knob really makes a difference at high mags.
