I've been playing for over forty years and I've had several fine instruments. When I find a guitar that I love, I sell my old one and replace it with the new. I am presently in love with a light as air Appolo flattop (it was made by luthier, Nick Appolonio, and it's the first handmade guitar I've ever liked). To afford it, I sold my 1973 Gibson B-25. It wasn't even close. I will never sell my 1962 Guild F-50. The best nylon string guitar I've had was a Gibson C-1, but it succumbed to age and neglect. As a rule, the Guild Mark series were terrific boxes, easy to play and inexpensive. The best value was Harmony classics made in the 50s and 60s. The 910 model was cheap and durable. You could use it as an canoe paddle and it wouldn't warp. Their 173 model was even better.
