Whist the FLIR is still out of reach... I ordered a CCTV camera with CS lens a few says ago. It comes with a larger lens than your average FPV board camera and the spec are already very impressive. But I can also use another larger lens which will substantially improve night performance.
I've been thinking about this since the word go as well, their getting smaller and cheaper. I almost bought one that supposedly came off a BMW as a nit driving camera that sits in the front bumper. Looked just the ticket but I was outbid in the dying seconds to a man whom seemed very keen to win it (he bid £1500). This is though more for my heating surveying with my quad than recreation RC but it wouldn't mean I couldn't burrow it from time to time, I should imagine it would be amazing for your night sorties!
