The Yamaha PSR175 keyboard is the next step up from the PSR 125. The student on a tight budget would be wise to choose the PSR175 to get started. Although a small keyboard, the PSR175 has a host of features including the portable grand button that instantly resets to a piano sound when selected. The Yamaha 275 is one of the best selling instruments of all time. It is great value for money and widely used in school music departments. (We recommend the Yamaha KPA3 mains adaptor to power up the Yamaha PSR 175. The KPA3 is an additional accessory not included in the price).
