I have never used them so I don't have any personal experience to draw from. For a business that has its sole business model as selling time on various telescopes, I personally feel that they could do a better job at eliminating some issues.
About 6 months ago an image from there was on here and it was noted that there was a glow on one side of the image that was caused by an errant light within the facility (could be seen on an external camera or something). This type of thing shouldn't occur when spending $100's considering how needless it is.
I do hear of comments about tilt coming from these telescopes, something that I personally would have thought would have been sorted on long term permanent setups. Whether they're flex or something else I am unsure.
That is my little rant on the cons, there are many pros too! I personally don't see myself owning a CDK20" any time soon so being able to use one of those beasts would be awesome. High resolution images from really good skies, who can complain with that
I personally get more satisfaction from producing images that I have taken myself but I can totally understand the whole getting tired of trawling gear around. I've had my mount outside in the glorious sunny days for the last 5 days, packed and unpacked the rest of the equipment 3 times in those 5 days and didn't get a single frame due to cloud (bloody Melbourne weather!!



). Being able to just have it work without all of the associated work.... It certainly has an appeal
