I've had a Naim Aro on my LP-12 (mated to an Ortofon Jubilee cartridge) since 2001. Sublime combo.
One small caveat on the Aro: unless Naim has changed things since 2001, it does *not* come with a cueing device, so unless you add your own, you will have to manually lower and raise the arm. I was able to buy a (no longer made) Naim Aromatic cuing device when I bought my arm. It's not without its foibles, but it beats manual engagement of the arm.
