We have a FLIR-1, which attaches to a smartphone and works pretty well for troubleshooting boards. It tries to get better resolution by combining the lowish-resolution IR image with a strongly edge-enhanced image from the phone camera, and then dorks the alignment to reduce the parallax effect.
It was about $400 a year or two ago.
