Phono Cartridge for $1,000.

Currently have Clearaudio Virtuoso MM cartridge . Wanting to go to MC. Found a Hana ML and a Sumiko Blackbird on sale for $1000. I am using a Musical Fidelity M6 phonostage so it will handle all. Is it worth it to change? If so, which one? I live in the sticks in Alabama so listening is almost impossible.
