I have a VX3 2.5-8 X 36. It's decent enough although I'd advise against a fine duplex. It tends to disappear in low light. The Zeiss Conquest 3-9 X 40 will do all you need and is reasonably priced. Another viable option is the 3-9 X 42 Sightron Big Sky. For superior low light use, I highly recommend the Trijicon 3-9 X 40. Although it's more expensive, the low light use is wonderful. Also, look at the new Vortex Viper HS line and the Bushnell Elites.
