I am untmost amazed at the fantistic performance of Casio CTK 7300 IN. Normally Casion keyboard will have lowest quality and standard compared to Yamaha or Korg or Rolland. Now these people started to go with the people and have improved the quality of the instrument. Not even beginner even semi professionals can manage with this nice and superb instrument. Even though both Casio 7300 and Yamaha PSR i455 are priced more or less, the former is selling Rs,2000/ less than the latter but having more features in it. even the sound quality of most of the tones are superbly equated with those of Yamaha. I may safely recommend those interested this instrument. No qualms in purchasing this product.
