There is a new thread here Mike put up with a little review of the HS1 I was referring to, FYI.
As far as Red Dots, it really is budget and intended use dependent. The Romeo 5 I referenced generally runs in the $100-$150 range. I have 3 of them and I like them a lot. It is not a high end red dot. I think if I was going to Afghanistan to combat I might pick a different one, but for my intended use, which is range and home/self defense, I have spent enough time with it that I would definitely trust my life with it. It has " Shake Awake", which means it shuts itself off when not in use and there is no need to turn it on or off manually. Some guys diss them, but you'll have that. I'd guess most of those guys never used one much less owned one. There is a torture video on YT. Believe me these things are tough, they stay zero'ed and they absolutely co-witness with most standard AR BUIS. They are NOT magnified so using them for 200+ range shots means you would need a magnifier.
Eotech makes a top shelf red dot. It's about 6 or 7 times more expensive than the Romeo 5.
