 Hi Jim,
 I've seen a few of these listed, but the problem is usually that they aren't rated for a high enough temp.  Good thought though.

I didn't know there was a serious temperature limitation.  I believe they're cheap enough and small enough that I'd be inclined to try one and see how well it lasted.
