Not sure how the OP was worded, but based on the replies I have a good feeling
Just a few comments....as far as red dots go, lumping all into this category, I have EOTechs and Aimpoints....I have used a friends Sig Romeo (I think that is the model, he paid $160 for it) and it was not bad.
As far as non-magnification sights go, I really like the EOTech's and if you are after an "open field" sight, then EOTech is the answer. Even with all of the bad press from about 4 years ago, I have never had an issue with an EOTech....I have the EXPS series...had a 512 about 15 years ago and it too was not an issue.
As far as Aimpoints go, I have the Comp M/ML 2, 3, and 4's in my collection and they are built like a tank, I really like the M4S. All are in Geissele mounts except one is in a GG&G cantilever mount
