A cheap but excellent scope is a Bushnell Banner Dusk to Dawn. You can get them in 1.5-4.5x32mm or go with the 3-9x40mm. You will find them clear, an excellent paralex, and light gathering ability.
This is the only scope I have purchased and dont think I will ever buy another. I bought it at bass pro for $100. This scope works very well way into the shooting hours when it is almost dark.
When I buy my Triumph or Encore this year I will get another Buchnell Banner 3-9 X 40 and put the Gorilla grips see thru bases on it so I can look through my open sights also. I didnt know that these existed until recently for some reason and have never liked shooting deer close up through the scope.
