Great bang for your buck - Meprolight M22 Rifle Sight

I think this is probably the best sub $500 optic. I like the brightness of the dot in situations where light from where you are is similar to the light where you are aiming, but every reviewer is right when they complain about shooting from dark into bright light. I'm told the $80 polarizer option corrects this, but it should absolutely be a huge asterisk for anyone thinking about buying the M22 who isn't shooting in perfect lighting conditions. It NEEDS the optional lens cover and should be sold as standard, regardless of what it does to the all important price point. I ordered the polarizing lens with the M22 and it was on a several week backorder. I should get it in about a week, and I'll do an updated review once I receive it. Bottom line: unless you're buying this for target shooting only, don't consider it a good optic for defense, unless you have the optional polarizer.
