Does anyone know where to get a keyboard fixed?

When I write a hymn arrangement I work with a keyboard that records so I can play the parts and the accompaniment at the same time and make sure it all fits together. When I add an obbligato, I need the recording feature even more.

Sadly, the record playback has stopped working, so getting out new arrangements is taking longer. I can’t decide if it would be better to try to get the keyboard fixed, or to invest in a new one.
