As a rule I try to buy a bow/instrument etc that I can readily sell at a minimal loss. Antique bows generally hold value far better than modern (just my experience). I’d rather have a
than something new….(not disparaging any masterful modern makers here ) Besides, what you like in “a great bow” and the next person will and can be radically different. If you are just trying to find the perfect bow for your playing (style,taste, sound,etc) perhaps something new might well work best.
