Maven makes great products. I ran the B series for a couple years and loved them. My buddy runs the C3 12x since they came out and he loves his.
The other brands I would look at in that price range would be the Meopta Optika hds. Also Cameraland has Athlon Cronus on sale too they would be another option. My choice in that price range would be the Meoptas with the Maven C series just slightly behind them.
