What to look for when buying a used thermal camera?

I'm going to go look at a used Flir E4 (want to hack it) in a couple of hours. What should I pay special attention to? Any quick "check list"? Physical damage is obvious of course.

Here are a few tips if you're using a site like eBay:

• Be careful of sellers with little feedback or lots of negative ratings.
• Be careful of listings that have only stock images.
• Check the history of the item with the manufacturer via the serial number.
• Ask the seller how long they've had the item and why they're selling it.
• Check completed listings to get a good idea of the market price.

This is true for any "big ticket" item.
