I must admit, Danny is right. There is a good days work in making a beam. You have a lot of work to do to the pickups, extending the arms and making it all line up etc..
Then you have spacers, rosejoints, powdercoat....all costs money mate.

I think the current market price for 6 degree beams is bang on the money tbh...thats why nobody is undercutting anyone as theres not enough money in it to do that.
