Essentially, you're paying the same per year buying the used CYPRES as you would a new one. So, it makes perfect sense to buy the used one if you'd rather not spend the extra money for new. With a fresh 8 year and batteries, the unit is as good as new from a functionality standpoint. By the way, I also have a used one, made 10/94 that is getting the update and batteries now. $450 includes USA shipping.
