One item that Tom (DSC) pointed out to me in a private e-mail exchange is that the particular Fuji PXR3 being offered by the Ebay seller can be changed from reading degrees F (the default for this model) to successfully reading degrees C. I have succeeded in doing this.
Now before ya'll start reving those keyboards up

, let me assure you that this particular model (PXR3RCY1-4VOA1) has a nice "degrees F" symbol on the faceplate and the Fuji instruction sheet accompanying this controller has NO MENTION of this whatsoever.
The parameter in question is entitled "P- F" and is the eleventh parameter of the 2nd block. This info is probably not too important for US customers but for others, it provides a means to make the swap in units.
