You can probably get around $50- $100 maybe more, for your F9 as is. As Tommyboy65 said, it is a very good cartridge. It may be one of the reasons you like records, so get the Shure and see if you want to have the F9 repaired latter. As you are finding, it is good to have a backup cartridge.
Fyi,Soundsmith has some ruby stylus assemblies for the F9 you may want to look into when you have some money.
