I have a Framus classical Guitar that I purchased when in the military in Germany back in 1975. (model 75A SN 01410-02202) When I bought it, it is was ~$200.00 It has nylon strings and still has beautiful sound quality which was why I bought it. It has stood up to over 35 years of abuse and is simple to tune maintaining tune over significant periods of time without use. It is easy to play and has a mellow sound.
I only found one guitar that I liked better and it was a Martin that a freind had spent $5000 on. I really liked the brighness of the sound on the steel strings which would reasonate in the instrument so well.
