I've got a continuing interest in the material designed and produced in the former Soviet Union, all of which is at least a generation behind comprable US-built NVDs, and generally isn't worth the additional hassle and lessened capabilities despite admittedly attractive prices...sometimes, unless your requirements are VERY specific and limited.
But one of the best in the business is: Excalibur Electro Optics. In particular, check out their *helpful info* section for a good overview of the subject and equipment available, and its capabilities.

do you (or anyone else) know of any good long-eye-relief models that can handle the increased recoil of a magnum handgun (454Casull)? I found one model, a gen3, that was around $2500, and that was with no bells and whistles. I could get by with gen1 sensitivity, but gotta have the eye relief and the shock tolerance.
