Not many optics at $1500 price range, that are great. If the PST2 had better quality control it would help. At least it has a nice reticle, and turrets and zero stop. Nightforce SHV F1 is not perfect either, short eye relief. XTR2 poor glass, Athlon Ares BTR is somewhere in there, but the ETR is the better one, but more money of course. Nikon FX1000 cheaper but sorta plain with less that stellar glass. SIG Whiskey5 may be ok, never see them around, don't think they warranty the electronic parts very long. All my opinion of course. Where is Leupold in all of this. Seems like they have nothing that fits in here. Lots of nice and clear hunting reticles, about it.
Higher end glass is always a better choice, however most people have a hard time coming up with 2-$2500 for one optic, (including me) let alone for all your rifles.
That 3-18x XTR3 zoom range is exactly what I would want.
