I've been through the same thought process ... I now have 2 night guns with thermal sights aboard as well
.
What about a low to mid end Zeus Pro ?? I'm looking at same ... the Pro line do have some nice features if you can find a good deal in the pile and the software is updatable without having to send it in.
The 2 power Zeus Pro 336, is showing on Optics Planet for around $5k with only $100 difference between the 30hz and 60hz ...
Armasight Zeus Pro 336 2-8x30mm Thermal Imaging Weapon Sight - 336x256 w/ Free Shipping and Handling — 2 models
I wonder why it is the 336 devices all seem to have twice the magnification as the "equivalent" entries on the 640 side (of the Zeus Pro Line) ??
2, 4, 8 for the 336s ...
1, 2, 4 for the 640s ...
