You could also check out the prices of the US dealers, they might have slightly lower prices than the on-line shop does for orders shipped overseas.
BTW, you US guys are spoiled by extra low prices. I don't say I'd be happy to pay $250 for a pickup. I paid ~ $190 for my raw nickel Nailbomb and ~ $410 for my camo Mule set, so $250 does look like a high price (not taking salary differences into consideration, though...). On the other hand, when we're talking about a guitar played for nearly a lifetime and a sound that inspires you every day, I think Bare Knuckle pickups are a great investment from an emotional point of view.
