Fluke just released a $1,000 camera, however, those are low resolution. Do a Google on a Fluke Ti25 (predecessor to the 125 or ti10), see if you can find a used one. I have some pics of a plugged cat, those are crazy.
Do you know of any somewhat decent IR cameras that are <$1k? I'd love to have one of those Flukes to play around with, but I can't justify spending that kinda coin on an IR camera.
As for sill heat, I've been reminded on a couple of occassions how hot they get, but it never leaves a mark on bare skin. If I ever remember, I'll have to grab my IR thermometer the next time I have it out.
