mango. The PSR5700 was a great keyboard in its time. My friend has only just sold his after many years of happy playing. It must be 8 to 10 year old now, but is still very nice to play and can be obtained used for about £250 UK pounds.
When new the 5700 was more expensive than a PSR2100 is now, however you can't compare this or any other older models from Yamaha because technology moves on. The PSR2000 or 2100 have far better voice samples and facilities and they sound a little nearer the real thing. But for anyone wanting a low cost outlay used board the PSR5700 can still perform very well.
