+1 for the MoFi Mastertracker. I love mine! Herb Reichert was impressed with it, as well: "I had never ever experienced such vitality and sharp focus from an MM cartridge. More surprisingly, this sharp focus did not come from lean, dry, or overdamped sound. The MasterTracker was simply getting all of the energy information off the record."
Regardless, make sure it's a good match for your TT, arm and system.
Good Luck!
