Mechans- I think the cartridge is a Grado Green Prestige. I would probably upgrade the cartridge at some point. I don't believe the particular ARC SP4 I have has a built in phono stage. I believe ARC put out an SP4-A that had the phono stage. I don't want to spend much more than $200, either new or used. I do have a fair collection of vinyl, but most of my investment is CD.
