I haven't had any PA optic but of course they have a good reputation for the price. I have one of these Sig red dots, which I believe is made by Holosun and therefore similar to (but not the same as) the PA:

That comes with an adjustable height mount for both absolute and lower 1/3 cowitness. In limited use I've been happy with all the basics: brightness, dot size, clarity etc.
The Vortex Crossfire mentioned above is not yet for sale but coming soon (I have one on preorder) and looks very promising. FYI though, the included mounts for it are either lower 1/3 cowitness or low, no absolute co-witness, and its battery life is not in the 50k hour range. On the plus side Vortex claims it's more rugged than the SPARC, which already had a good reputation for that, and the selling price is in the $130 range.
