My main table is a Dual 1229 with a Grace 747 tonearm. The Dual stock tonearm is actually very good. I love my Nagaoka MP 11 Boron, Denon 103R, I have several Audio Technica/Signet's that are equally wonderful. And yes, Zavato nailed an excellent choice in the Shure VI5 type III, type IV or V should work perfectly.
Honestly, I really can't think of any cartridge that wouldn't work well in the stock Dual tonearm. Get several extra drop out headshells and swapping cartridges is a breeze. If you need help maintaining it, let me know. I've rebuilt many.
