Yamaha psr630

I love the sound that the speakers produce on this keyboard and the easy transpose button since I don't know the many chords except one that I had favoured to use for the many times that I play

This keyboard had a problem of getting locked up to a sound then drags on till I turn it off. It would take a few on and offs to get the it back to normal then after sometime it will fault again
Is there another model that is comparable to this one?
