If you think you'll enjoy the challenge of star hopping and hunting down DSOs, then forget the Argo. By learning 'manually' you'll get an understanding a appreciation of the night sky. How long that takes is dependant on a number of factors, darkish skies will go a long way of helping, the size of your scope (8" vs 12") and obviously your navigation skills and patience. Patience is arguably one that defeats many!
Having said that, an Argo is a fantastic piece of gear and worth every penny. Its makes observing so much more rewarding. Garry Knopff (Wildcard Innovations) provides EXCELLENT service and you wouldn't have any regrets getting one.
In fact, I'd say the Argo comes close as the 2nd/3rd most important piece of gear I have, apart from the scope!
