Re: pickup value
You can buy Duncan Performer Buckshots (same pickup as the HB103, just the name for the aftermarket ones) for $30 a pop from Guitar Center. By that logic, a brand new set would be $60. People typically sell used USA Duncans for $45 to $50, when they're approx $70 or so new.
I'd say $45 shipped for the set is a fair price. You're probably gonna have to undercut yourself a bit just to get someone to bite, considering the negligible price difference between the imports and USAs.
