haha well you've come to the right place.. We've had 3 or 4 members in the last 4 weeks who have bought the 8" GSO Dob.
They all give great reports of it, look for posts by Frosty and MintSauce for starters.. Ving also has one and has owned it for a while.
I have the 10".
They are great scopes for the price - read
this thread where Jimmy is pondering the 8" GSO dob and there's a lot of good arguments why the 8" is a great scope.
If you're unsure of anything, just post again and there'll be plenty of people willing to help.
