If you are considering purchasing a GSO RC and have reservations regarding the quality of the focuser, bear the following in mind:
Your imaging requirements can be SIGNIFICANTLY different to the next persons. Do you intend to only connect a DSLR and use a separate guidescope, or are you putting on an imaging train consisting of an adaptive optics off-axis guider, large capacity filter-wheel and a heavy large-format camera (800g vs 5kg or greater). The market for these scopes is comprised of people just starting out with DSLR's (or even guide-cameras) to pretty sophisticated setups.
If all I was going to use was a 800g DSLR (Canon 450D), I would be turned off the purchase if I had to pay for the top-end quality focuser that would be required for the heavy imaging trains some guys use. Where do you draw the line? Focuser good enough for 1kg, 2kg, 3kg, 4kg, 5kg.... It makes perfect sense for the manufacturer to cater for the lowest common denominator, then give the user the choice of their own focuser that is ideally suited to their own needs. So the real question is: is the stock focuser good enough for a DSLR with nothing else?
I would be quite happy if they sold the scope without a focuser - but what do you do when it is delivered and the preferred focuser is still being shipped? No playing then with the new toy....
