If you are looking for a reasonably priced IR camera, look for the Fuji IS Pro, but look quick because Fuji just discontinued it a week or two ago, and they are selling fast. --- Finally makes a cool camera, and then cancels it. I think Fuji is dropping all the DSLR stuff and just going to be selling point and shoots.
