I recently got my 10" GSO Dob from Andrews - good people to deal with, and carry out the tube every time I want to view, it's 15+Kgs, then there's the mount (swivel base assembly), another 15+Kgs. Not unmanageable and at least I know it's all safe in the house afterwards. I was considering bigger better eyepieces and filters etc., but after posting a thread I decided to use what I've got to see what they can do, and how I can observe better with them. What I'm trying to say is don't rush in and spend on stuff you really don't need until you know you do. Good luck
