Stick with your bigger names like Nikon, Burris, Leupold, and Bushnell. All have a good reputation for good optics and you can pick up a Nikon Prostaff or Leupold Rifleman for about $150 +/-. Trust me it's worth the $ to spend a little more on your optics. I replaced several "cheap" scopes within a few years and spent about $250 doing it. I would have saved myself $100 or more if I would have listened and saved a little longer to get a better scope.
