Rega P5

Hi,
I'm new here and to the "high end" world of turntables and I need some cartridge advice. I'm putting together my new system and just picked up a used Rega P5 minus a cartridge, my previous table was a Technics AL-L2OR with linear tracking (quite the upgrade), needless to say I have quite a bit of catching up to do and alot of questions to ask. I also recently purchased a used Quad 34 preamp (my previous preamp was a Hafler) to go with my Quad 405 and DCM Time Windows. The phono module in the back is marked with a value of 100uv. What does that mean and how does it relate to the cartridge output? I think the module is for an MC but I'm not positive. If it's for an MC, can it still be used with a MM? I've read some positive reviews using a Shure V15VxMR or Dynavector 10X5 with Regas. Can either one be used with my setup with good results? Are there any other used/new cartridges in the $200-400 range that would work? Will the phono module in the Quad work with the newer cartridges or do I need a phono preamp?

Thanks,
Bill
