Best deal I've found so far...the Flir1 for iphone

[Ron Wickersham]

Now only $250.00 for this infinitely useful doodad. It's a thermal imaging add-on for your phone.

Has anyone used one of these yet? Seems like a great way to diagnose heating and cooling issues, check your insulation, find hidden water leaks and mold, helpful to find wall studs, and look for electrical problems.

I'm adding this to my wish list even if it is a doodad.
