Illuminated reticle is overrated, IMO, as well. I've had plenty of them, and never used them. I also have 3 HST's and an HS. Vortex makes great optics, even their cheaper stuff is better than the mid-grade stuff of yesteryear. And their mid-grade stuff (HS, HST, etc...) is on-par with the $1,200 scopes of just a few years ago.
If you've never looked through an HST, you should. The only differences in the HST vs. the PST is that the HST has a wire reticle, and the PST has an etched-glass reticle, the PST has illumination, and the PST has different reticles. Other than that, they are the same exact scope, same glass, same lens coating, same turrets, same scope body, same everything.
