Hi OzStarGazer & welcome !
Great to hear your decision to get a scope.
Its good you are considering useability as that is one of the key issues.
An 8" Dobsonian is the Standard advice, but you would not want to lug that around without a car.
That said I find my 4" tabletop scope gets more use than all my other scopes put together (yep, got a few !)
This
1st telescope article I have written may be helpful too you too.
PM me if you want to know more.
