Patrick has given a good option to grab one second hand and save some dollars and get something decent.
Usually the sellers are willing to show you how operate the scope unless they are selling for someone else.
If its a first scope, I recommend grabbing it from a bricks and mortar store. Can't beat first hand knowledge and demonstration on how to use the scope.
I know its exciting the first time you head outside to use the scope. Just want to highlight some of the stuff to avoid frustration and what kills the euthusiasm. I have acquired a lot of scopes second hand from people who didn't know how to use the equipment.
All the best, please give us all an update on what you pick
