JMI EV-3c
I got this single speed focuser for my 14" LX200 so I could have smooth easy fine focusing. It works great, the only drawback is that the 14" Scopes have limited clearance in Alt Az mode. I tried a few focusers and this one comes closest to clearing the base when pointed at the zenith. If it was 1/4" shorter it would be perfect. I just have to remember to run the focuser in before slewing to an object near the zenith. Well made and good looking.
