Any Wing that does not Have "AMF" or "HEAD SKI" on them is good quality. They are all decebt shooters, but the earlier wings are the best. After Bob Lee sold the company, the new management focused on noney instead of quality.
The value issue is the same. Early Wings are worth more.
As far as how much they should cost, the best thing to do is to go to e8ay under compleated items and see what they sold for.
The one listed above went for $86 but I did not see if it was an early model or not.
