Where does the wear and tear occur on these? How long do they typically last? What is one advised to look for in a used one? Let's say one is in good condition with no visbile defects, what percentage of the original price is reasonable? They're little over 300 new, I seem to remember.
Can a person improvise and build something that mimics the head and neck, with reasonable materials, skills, and time?
Thanks
