Ok... the brutal truth is...
The guys from Throbak, Lollar, Amber, Haeussel and BKP have all done their research and they all make good pickups. Obviously Tim and Harry (from Haeussel) are much better at bookkeeping and running a business efficiently, because they manage to sell the pickups at a much lower price and still make a profit!!!
I bet Lollar has some horribly high labour costs and a very low output. That's probably where the problem lies. The parts and machines costs more or less the same what they cost any other pickup manufacturer. Even if they are higher, the effect isn't that huge, because in the long run fixed costs approach 0.
If Lollar managed to exand and increase his output, he could probably sell them cheaper.
But no one should really claim that a product is higher quality or better because it is more expensive, when most likely the extra money you're paying is mostly simply for the fact that it is made by a very small company which cannot make the savings of a bigger one, by a guy who loves what he's doing but doesn't really have a lot of business knowledge behind it. £399 for a set of pickups strongly suggests that!
