depends what your going for though really, the full GSO setup with pc control probably works out to cost a little less than a JMI motorised focuser.
the way i see it, once motorised it wouldnt matter if the focuser was a gso or a feathertouch, its going to work the same way since the motor wont care how smooth the motion is (aslong as there is no slop in the drawtube).
it took a bit of fiddling to get it set the way i wanted it but once it was going, it was worth every cent
