I was in the same boat as you. Couldn't see spending $100-150+ on a red dot for a .22 that's used primarily for plinking.
I wanted a reflex (open) style vs scope style for more peripheral vision, which ruled out a lot of options (I'm still not sure if that was the correct route).
Anyway., I chose the Mueller Quick Shot and got it for $95 shipped with a free tshirt and decal from joeboboutfitters.com
Mueller Quick Shot? 1×22×33 (Black) - Mueller Optics
I couldn't find any negative (or positive for that matter) reviews on the various forums and such, but I went for it anyway.
Apparently, Mueller is more known in the Turkey hunting world. I figured if it could handle a turkey gun it could handle my .22 .
All that said, I can't compare it to other red dots because it's my first. But other than reflection in certain light situations it's spot on and I love it. I'm hoping reflection/glare is an open sight problem regardless of brand, but I may be wrong. Hopefully someone with more experience can chime in.
