The following is just my ignorant, one sided opinion.
If you want a red dot sight, as far as I'm concerned, the only option is an aimpoint. Eotechs are nice, and some people really like the reticle, they even have one with bullet drop, but they are far more failure prone, and the battery life sucks in comparison. I have personally seen eotechs fail, and once was not under what I would consider hard use. We've all seen the daniel defense torture test video by now, the aimpoint gets blown up, has it's glass crack, and still maintains zero, only dropping it out of a helicopter makes it lose zero. They also have a battery life measured in years of constant on, they are at the point now where you replace the battery almost as often as you need new tritium in night sights. Yes, they are more expensive, especially when you consider that they often require a +/- $100 mount for an AR or similar rifle with a high height over bore, where as eotechs do not. The new aimpoint pro is around $400, including a mount, and the micro r1 (silver version of the h1) can still be had for around $350.
My way of thinking in general with this kind of stuff is that I'm too poor to buy cheaper stuff. If I buy cheap stuff, it will fail on me more often than not, and I'll end up buying the more expensive thing anyway. I have boxes full of cheap gear, optics, and parts that cost me far over the long road.
