Sue's bows are often regarded as the holy grail of bass bows. I have heard similar things about her rehairs as well.
Lynn Armour Hannings (lahbows.com) is in Maine. There are some exceptions, but most of North America's bow makers/repair people have studied with Lynn. (Sue Lipkins and Lynn both studied with Salchow in New York, Lynn went on to study with Bernard Millant in France) I cannot recommend her bows, repair work, and teaching enough.
