Eureka USA has really nice stuff. Their chaos dwarves, snake men, fantasy African, and lizard men are all complete armies. As mentioned the others make for great add-ons to other ranges.
Rebel Minis has a small selection of stuff--orcs and wood elves.
Microword Games is 6mm but some of their stuff works well in 10mm.
Copplestone, Pendraken and Magister Militia are great to work with and the shipping is not too bad.
