There were a couple of things i didnt like about the GSO CF newt (apart from the wrong mirror being installed), its that collimation was an absolute hell. Not just because it was an f4 but the collimation screws themselves are like butter, they'll strip clean if you're not careful. If you are intending to get it, I'd suggest either install bobs knob (or equivalent) or replace the philips screws with more sturdy ones.
