tonearm for a kenwood kd 650

i bought a kd 650 tt for my son but the tonearm got trashed . what arm could replace it. i would like to put a rega. any thoughts?
Dear Coffe2: That's very nice TT where you can put almost any tonearm depending much on what cartridges you want/own to use. It seems to me that the only tonearm limitations that you have is your budget, which cartridges and the hole distance to the spindle that the TT already has.

Regards and enjoy the music,
