Roland has launched only one keyboard in this price range. I wanted a keyboard with priority of better sound and tone quality than number of functions available. Sound quality is of this keyboard very good; better than casio as well as yamaha; I have played all three in the music shop before buying. Build quality of this keyboard is above average and not the best. Size is compact which is a pro. Keys quality is very good. This keyboard has a unique sustain button also available which no other brand offers; we can use this button to have sustain function without the need of additional pedal. This keyboard have good number of Indian styles. Indian tones such as sitar, santur, flute are very good comparing to yamaha or casio. This keyboard has one more unique button of Fade In/Out which can be used in Intro or Outro. Its, arranger functions is very good, it just synchronizes with our play style and provide good backing track with just a touch of a button. Overall this is the best keyboard with very good sound quality with most of the functions available for beginner to intermediate users. If sound quality is priority then this is the keyboard to goto without a doubt.
