I like the factory Dunlops the best and are the only ones I stock, D401 100/19 Front & 130/90B 16 Rear, they cost a little more then the D404 but tires are no place to save money. A lot of local riders also perfer Dunlop's Elite 3's, also a good tire. A very good place I've found to order from that gives free shipping on orders over $100.00 is Jake Wilson.
