There are three things to consider when purchasing an instrument: sound, sound, and sound. Next in order of importance are playability, appearance, and cachet/sexiness.
I have never bought into the old instrument mystique. Antiques of any sort do not excite me per se. Whether it is a dining table or a banjo, to me it is just somebody else's used stuff. I could get excited about playing my own grandfather's guitar (if he had played one) but I cannot get excited about playing somebody else's grandfather's guitar Because of the cachet of certain old instruments, IMHO they are not a good value speaking strictly in terms of sound. I've played too many modern instruments that sound as good as or better. I also don't buy the "They don't make 'em like they used to" line. If anything, they make 'em better.
