Our verdict
Ask experienced observers what they'd hand a serious beginner and a Dobsonian comes up every time. You're paying for the mirror, not a complicated mount, so every dollar buys aperture. The trade-off is no tracking — but learning to star-hop a Dob teaches you the sky in a way GoTo never will. For pure 'how much can I see per dollar', nothing beats a Dob.
