Someone who deals mainly through dealers is unlikely to be cheaper buying direct unless you are willing to wait many years. They will not want to undercut the dealers who are their bread and butter, so you will be bottom priority. If luthier X is represented by (say) say 6 of the 20 top dealers in the world, then what incentive is there for them to talk to anyone else? Apart maybe from a world class performer who will make their instruments even more desireable?
