I have the 8" gso rc. I've been very impressed with it. The only mod I think I'll end up doing will be getting a moonlite focuser and replacing the stock 10:1. It seems to hold collimation fairly well too. Nothing bad to say at all at the moment.
The metal 10" RC is ~ 12-12.5 kg in weight - the same as a 10" Meade SCT.
Run both of these OTAs on an eq6 if that helps you with 4 counterweights and a guidescope (72mm) and ccd camera.
