Hi Daniel,
Les Dalrymple of AS&T fame (NGCLes here) did a comprehensive SW980 solid tube evalution in the AS&T not too long ago, where he praised the quality of the Skywatcher's optics in being able to split Sirius A & B optically as well as resolve the smaller details on Saturn compared to his Mark Suchting (hope I spelled it right) 12" mirror 31cm dob and it did very well in comparison. I dont know about the GSO optics but from all reports, they are very good and perhaps on par with the Skywatcher ones.
Have a quick search here for Les' posts and you will turn up the reports and his comments on other threads re the 12" SW980.
Cheers
Chris
