The Orion mounts are, I believe, Chinese sourced, as are the CG-5s. If I was to go with an Orion mount, I'd probably get the SkyView Pro since the steel tripod would be much nicer than the aluminium tripod of the AstroView, and I believe the head is more robust as well. This was one of the mounts I considered. I also considered the Atlas mount before I got my Vixen, but I thought it would be SERIOUS overkill for my Mak (and I wasn't too keen on built-in motors).
The SkyView pro looks a lot like the new Advanced Series CG-5, which, with the CG-5, is more or less a copy of the Vixen GP. I believe the Vixen uses ball bearings while the copies use bushings, and there are other detail differences that may affect performance/durability.
I actually use Celestron motors on my Vixen as they were several hundred dollars cheaper, though they only go up to 8x tracking rate. I do major motions by unlocking the clutches and slewing by hand, and fine control with the slo-mos. I only use the drive corrector for tracking and fine centering. Doing a quick polar alignment with the included polar alignment scope and illuminator is fairly easy, and it will track objects for hours with only very minor recentering. I will say I'm not disappointed with the GP.
Figure $329 for the SkyView, plus $100 for dual-axis drive corrector, plus $50 for a polar alignment scope, $30-$50 for an illuminator, and your at about $529. That's against $800 for a GP on a good aluminium tripod, plus $100 for motors. Less than twice as much. Is it twice as good? Probably not, unless you are doing long-duration photography, and then the GP is considered by many to be the minimum.

Good luck with your decision!

I suppose it depends on future plans. That Atlas mount is a heavy bugger to set up if you don't need the extra capacity. That's the only reason I let mine go.

I am interested in buying the GP. I already own the Astroview and was wondering if it would be possible to attach the GP mount to the Astroview Tripod. My plan is to buy or make wooden legs in the future and would like to save the expense of the AL150 for now.
Your comments are appreciated.
