All good.
I would use as a guide what you want to view. Hard question to answer at the start.
Basic criteria I would use:
Price
Aperture
Portability -size/weight
Manual/Goto
The dobs are generally the best bang for buck and I have found for myself an easier learning curve.
I remember talking the guys at bintel in Melbourne about buying only one scope, they just laughed at me and said they have heard that statement before
