Almost any cart that tracks at 2 grams (mN) will work. Beware lighter trackers, as they have higher compliance than that arm is good for. Matching a cart mechanically is easy, but sonically, it depends on your musical preferences, accompanying electronics, speakers, etc. I agree with Jr. that AT makes a good all-rounder. While the Sumikos lack the advanced stylus specs (nudity, line contact), their generator is excellent and plenty of listeners love them for their "warmth" and excellent tracking. Consider a Rainier as one of your options. For a Grado, I'd look at the Opus 3 if budget allows. It gets a lot of love.
