cartridge for Rega P3 or P3-24?

I'm trying to talk myself into a turntable to play my old records. When I was an impoverished student, I told myself that I would (maybe) buy an NAD turntable someday. Now I'm starting to think about finding a used Rega P3. I've noticed some of these with the newer version of the Elys cartridge, but I was wondering if a Denon or Dynavector might be a better choice. For reference, the rest of my system is as follows: NAD C541i CD player, Audio Research LS3b and D130 amplification, Vandersteen 1b speakers. And I was thinking of the NAD PP-2 or Cambridge 640P phono pre-amps. Thanks. . .
