Before buying new stuff, particularly musical instruments, better research first online about the brand and if it has durable quality. This applies not only to professionals but to hobbyist as well, or even to the neophytes. But if you are still not sure what or where to find, perhaps I'll recommend Casio privia reviews to you to help you look for better option.
Good luck on your choice and purchases. I hope you found the right instrument that really suits your taste!
