What are you after that eotech offers?
If you just want a good, rugged red dot, it's hard to beat an old aimpoint Comp M2 and they can be had cheap off fleabay.
If you want the circle and dot reticle, meprolight/mako makes a unit. Trijicon also offers that type Reticle in their low magnification mini ACOGs
