I'm partial to the Burris Fast Fire II myself. It gives you that "open" style sight picture you are looking for and is more affordable (I've seen them as low as $176 USD online) than an Aimpoint. I believe NC Star makes a similar reflex scope. Anyhow, I use one similar to the Fast Fire slightly offset with my telescopic sight for that "just in case" need to rapidly acquire a target, whether it be paper or coyote...hope this helps some!
