Considering what they are I don't think the price is out of line at all. Yeah, they're not cheap. Then again (if they turn out to be what's advertised), you're getting a 1/2" 60's Gibson Thunderbird pickup, with correct cover (made on original tooling). Yes, I know, it's not actually from the 60's. Close enough for me... What would an original in mint condition run you? I've seen one Chandler go for $300 and those were never represented as 60's replicas.
I don't see these as ever having been intended to sell to a large market, but for the few guys that really want that pickup, these just might be the real deal. Once the good Fraulein has hers in hand, we'll know.
