I don't know what the early models were like, as I haven't seen any. GSO say they now test the optics pre and post coating.
I have tested a number and would have been happy to own any, though I did seen some small sphercial error variations: to be expected in any mass produced optic. Anything gross I would send back.
Bright stars just outside a camera's FOV can cause stray reflections, but again even a 40K RCOS will do that.
I've found the build quality and consistency to be very good.
My only minor gripe would be the 10:1 focuser, the new ones have a linear bearing with minimal slop, but using the 10:1 reduction knob to lift a heavy camera, it would slip (the work around was to use the 1:1 uphill and 10:1 down)....but again, even my AP/feathertouch is a bugger to use with a STL+FWL+AO.
To be sure they are not an RCOS, but IMHO are not shabby either.
