Need a stylus for my old Magnavox...

Anyone know where to get one? It's a model # 3RP657 and it seems a shame to get rid of it. It looks brand new and the radio part works like a charm! I use it to play my collection of 78s and I love the vintage sound. It's not hifi by any stretch of the imagination, but it's fun for the whole family.

If I can't find the right stylus, I'm going to be forced to gt rid of it and then I'll have to buy a 78 only TT, monoblocks, and hook the whole rig up to my Hornshoppe horns!
