For the $200-300 price range you can't beat the Vortex Sparc. You can find them new for $200 and they come with multiple mounts for height along with the lifetime guarantee. I've been running one for about a year for a cheap optic on a training rifle/lender rifle and could not be more impressed. Next step up from that price range would be the Trijicon MRO. Shot it in January at Shot Show next to an Aimpoint and the increase in field of view was extremely helpful in close range. Takes time, but you can find them for just over $400 with a mount if you look around and are patient. Just depends on what you want to use it for and your price range but with what you stated, the Vortex Sparc is the best for the money to me.
