I have a fully automated 2.3m dome and it has been very good. However, it was designed in the day when an 8" SCT was massive and the need for guide-scopes were beyond the amateur.
The dome opening needs to be seriously widened to make it competitive these days. I spoke to the original owners about this and they were not interested. They went bust - quelle surprise!
Another story of a great Aussie company failing to invest in it's product. I really hope the new owner (OwenSirius) re-invigorates the brand. I'm away on travels for a few months, but I'll invite you (Owen) to my observatory and give you some tips for consideration when I get back to Brisbane in the new year
