I, too, hope he can get a deal.
I did not even know until minutes ago that three diode chips are involved. Yeah....how cool. I don't know what I would use of the infrared or the red...but probably would like to check out as much as possible of both.
That other thread has a link to a description of the diode setup and how to deal with it. Apparently, it is a terribly high strung house pet, _very_ sensitive to ESD, just begging to drop dead if you even think of frowning at it!
