That is my meaning exactly, the EQ6-R belt drive is a big advantage over the gearbox driven versions. I would personally leave the reduction gearbox versions for visual use.
I know of someone who has spent a lot of time fiddling with worm gear mesh and end float, and also tweaking the reduction gears as best they can on an NEQ6, and PHD2 still suggests a backlash compensation in the region of 1200 milliseconds! It has no detectable Dec backlash at the puck, most of it is coming from the reduction gearbox and it makes guiding quite hit and miss.
