I am using a Yamaha CG-150SA. Solid Top. do not know about back and side. I paid RMB3,500.00 including the box. I think it is a very good guitar. Much much better than most of the China made guitar I bought like Hongmian, Xiezou....
CG-150SA is the old Yamaha series. Made in Taiwan. Better than the current CG-151S. Equivalent to current CG-171S. The price is around RMB4000.00 in Beijing. Japanese products are basically medium quality with reasonable pricie. It is much better than the China made demostic plant Guitar.
If you are just a starter, I recommend you to buy a guitar like cost you within RMB1500.00. Maybe 1 year later, you may upgrade to a guitar cost you RMB6000 to 9000.00.
Yamaha is good medium quality guitar but no good for pricing since they have to pay tarriff on it.
I found from Yamaha website that they stopped making Classical Guitar in Taiwan and moved it to Indonesia. I guess becasue Taiwan labor cost is too high for th elabor intensive job like making Guitar.
My Yamaha is made in Taiwan and I think it is pretty good. Do not know about Yamaha made in Indoneisa. Never tried before.
