Night vision

I have always been interested in wildlife and have several pairs of
binoculars ranging in size and magnification and have use them at night also
lamps, but I really would like some good night vision gear. Could anyone
advice me on what's good and what's not in night vision equipment, the main
things I will be looking at will be badger, fox, owl, deer, but any wildlife
really. Any recommendations from those with experience would be very much
appreciated.

Thanks,
