Do I need just a new shaft or complete motor?

Hi,

My Gyre XF-230 stopped working yesterday and when I pulled things apart, it would not turn. I pulled out the shaft and the magnet is split and is no longer round. Do I need just a new shaft/magnet or does this mean I need the motor housing along with it? I've had this for a while, so it is not under warranty.

Thanks in advance,
Mark
