IIRC the P-3 has an AC motor. England has 50Hz power so you'd have to change the motor for US 60 Hz.
There's always a few good Regas on Audiogon from US sellers and Audiogon has been berry, berry good to me. The P-3 is an outstanding table, the P-5 and up even better. I'd go that way and not worry about the motor.
