Hello,
I use the Nagaoka 110 but not on a Rega. My cartridge is great. I have heard you want to be careful in picking out a cartridge that works with the rega line. Sometimes when the cart gets close to the motor you can get some ground loop hum. I would pick a rega TT despite this little problem but make sure someone is already using the cart on an unmodified TT or use what rega recommended. Because carts are not typically returnable I would make sure it is going to work.
