Which tonearm should I keep?

I need to sell some audio gear for funds to pay for a pre-amp upgrade.
I need to sell soon, so I don't have alot of time to sit and compare between them and would appreciate very much what others views, thoughts and opinions would be on the one to keep.

The tonearms are:

Hadcock 242SE Super Silver (currently using)

(2)Technics 500 one a501 E, one 501 H arms)

Fidelity Research FR64

Fidelity Research FR64S

My cartridges:

Music Maker III (currently using)

Fidelity Research MC201
Fidelity Research FR-1 MK3 F

Dynavector KARAT 17D2 MR (considering retip)

Ortofon 30 (considering retip)

Cartridges are flexible, as I can purchase different in the future, I just want to sell the extra tonearms.

I would greatly appreciate suggestions on which one to keep.

Thanks...

Rick
