This is my rule of thumb and I don't expect anyone to follow it but me. I believe you can get a good 3-9 scope for $200.00. For a 4-14 scope I wouldn't spend less than $400.00. It costs a lot more money to make a good scope with a 4-14 zoom range than it does to make one with a 3-9.
I also don't believe Vortex markets a Diamondback in 4-14x40.
