Does anybody have any experience with one of these? I can't seem to get mine to work properly. When I try to focus on a bright star seems if there is any atmospheric disturbance, which there always is, the bars are swimming so badly it's impossible to see them much less focus. I may not have set it up properly, the instructions are kind of vague. Anybody mastered one of these things?

Yes, I have absolutely no problem with mine.  The lines are sharp, and come to a focus easily.  It sounds like you are seing tube currents or poor atmospheric seeing.  Your scope needs to ready for photography, that is, cooled down, Polar aligned (no tracking problems), and no dew.
