I'm inclined to agree with Stevecham's comment that you won't go wrong with the Shelter 501 Mk2. It's a fine cartridge, particularly for the money, and I strongly suggest you audition it before you make a decision.
That said, I own a Grado Reference (the 4.5 mV output version), and I love it. It is very musical, has great bass, smooth frequency response, very good detail (but not clinical, like some MC cartridges), and -- to my ear -- really excels at accurately reproducing the tonality and timbre of instruments. It also has excellent transient response (tho' not as quick as the best MC's) and fine sound-staging. To get better performance, you will have to spend around $2k.
The only "deterrents" to the Grado Reference are its susceptibility to hum (from proximity to the drive motor), and the need for a dead-level platter (otherwise, you may experience the "Grado bounce"). Mine tracks very well at the recommended 1.5 grams.
