True, I know only one person who plays a French bow made by Hoyer; he had some copies made of his own old French pedigree bows (which it is safe to presume are still his main bows).
You'll quite easily find a French or German bow by one of the Döllings for about €2k and slightly below, although I see why that would appear as too cheap a solution to some people (which it probably is).
I was just making the point that this is where you will start getting bows made by a real master maker; isn't this what the word "master" refers to?
