Ok here's my opinion and I don't even own a scope!
From what I've read over the last several months, my own research, pros/cons, portability, transportation and finally cost...... I think the 10inch GS dob from Andrews with crayford focuser and built in fan. If you can afford the extra $$$ go for the Bintel Premium 10inch dob for peace of mind (pre-checks, collimation).
Whether its pre-collimated or not, its something that will need to be learnt and mastered with dobs.
Thats my 2 cents worth.
fwiw: portability (car limitations) is my biggest issue so I'm holding off until the 12inch Lightbridge or 16inch GS Truss dob past muster before I commit.
