I've got the D-760 GenIII, a PVS-14, as well as a Mil-Spec PVS-22 just reently purchased for over 8K.
A 3rd Gen D740 is the best "budget" option, but I have a feeling the Wasp will be the way to go.
If I was in your shoes right now, I'd get a mil 3X for the 14 and wait. Even if I could afford a Raptor.
UNLESS you are planning on a clip on, in that case buy it now, while you can get a mil spec unit.
I could not be more thrilled with my OSTI AN/PVS-22. I thought hard about the 27, but I'm not that long range of a shooter, and it is a lot more and bigger than it looks.
But it does work well at magnifications much higher than the 22 can handle.
I did want more than the smaller UNS SR delivers (pretty much a 4X unit), so the 22 was the best choice for me.
The best setup would be the UNS SR AND the PVS-27, but holy crap, with that you have just gone from 10K to what, 16-17K?
The "civi" UNS (BNS) is nice, but lacks the gain control, I'd sure hate to give that up to save 1K.
My D-760 GenIII lacks one also, my only complaint about the unit.
