I'd love to but way too far.

If you go the Gen 2 route, make sure you specify you want a Photonis tube, preferably something close to XD4 spec. If you are willing to live with a few dots in the image, you can get a unit with near Gen 3 performance at a Gen 2 price point. A nice, high quality Photonis Commercial Grade Tube is, basically, one of the best values you can get when buying in Canada.

I was actually thinking about building a custom unit with an XX1441 tube. What do you think of this one ?
Typical performance are FOM=1340, S/N=21, Sensitivity at 2850K=650 and 64lp/mm

My concern is about very low light conditions, where Gen3 seems to be much more sensitive to light.
On the other hand, Gen2 is more rugged ...
