The model I have is 3 years old. Never used. They are brand new $1300 + HST at Costco though I admit I paid less elsewhere.

I really don't know what they are worth second hand but any serious offer i'll entertain. Its in its original red hard case and the interior has never been touched. (Plastic on everything still) Full disclosure,in training I was told they are supposed to be calibrated periodically though they still work fine without.

This is the model I have:
