It's good if parts can be sourced here in the UK because the G&L online store charge $25 for every shipment, no matter how small. I complained about this because my guitar arrived and the little allen screw was missing from the vibrato arm, so I attempted to order some for about £3 and then saw the delivery charges. I got a nice email from Chris Robosan telling me that he agreed about the shipping costs but it was a third party that ran the online store and G&L didn't profit from it, but has agreed to send some screws & nylon bushes for free. You can't get better than that.
I had already sourced some allen screws from a friend who works in the engineering trade, they are 4mm metric.
