I have a GSO from Andrews Communication and it's fantastic.
It's a bit heavy, but I don't use my 4.5" newtonian any more
because I'm always disappointed at the views compared to my 12".
Takes me 5 minutes to setup from opening the back door to
plugging in the fan and taking the lid off. And that includes dodging
kids toys, over active dogs and clothes lines that become mysteriously
invisible in the dark. (gotta watch that finder scope, makes a fantastic
hook)
The first time I looked through mine I couldn't believe how many
stars were up there. Even after scanning the skies with my
4.5" newt.
Go the 12" dob.
