I used to have some PSR Yamaha series, then I bought a PA 80, and hold a PA 60 for three years. A friend of mine bought a PSR 1500, I tried at his place I did'nt like its quality of sound. Then I was about to buy a TR series Korg, but after playing it at the Store I was really dissapointed in going on with the idea of buying it.
Then I make a good decision (since my point of view) I bought a PA 50, and I find it very good. It has many improvements (in comparison with PA 60/80 and the same good sound effects. I love the Folk Sax, the flute, the nylon guitar, the sweet harmonic, the piano,etc.
In my city, Trujillo-Peru when I play on receptions and weddings people and musicians are atonished about hearing to my new keyboard.
So, now I have a good synth by paying less.
