I'll second the Shure V15VxMR. Really hard to go wrong with this cartridge and you get the added benefit of being able to remove the stylus without removing the whole cartrige. I found this of great importance when cleaning, moving or modifying anything on the table.
You may also want to consider a Dynavector 10x5. I have not heard one but the 10x5 seems to be preferred by many to the Grado.
