I got a house full of them and so gotta agree. But you also have to do your homework and know what you are doing if you head of in this direction. Not only are there often issues with old guitars you need to look for but there are vintage guitars and there are vintage guitars. They ain't all created equal and age is no guarantee of good sound.I like what zoomby said.
Don't forget to add vintage to your search. Lots of good vibes coming out of these old girls.
