If I wanted hatchery chicks, I'd go to my local feedstore. They buy in large quanities from the hatcheries and our's is pretty good about ordering lots of rarer breeds.
Otherwise, if you have to order on your own and don't mind the minimum number, McMurray's is probably as good as any. They also give very good service. I've ordered supplies from then several times. They frequently give free shipping on dry goods.

I don't mind ordering a minimum, actually I'd planned on ordering 36, mixed breeds: 6 Rhode Island Red hens, 6 Speckled Sussex, 6 Jersey Giants, 6 Silver Laced Wyandottes, 6 Dark Brahmas, and 6 Silver Penciled Rocks, and one Phoenix Roo. I just love those tails! The RIR hens are for my grandmother, who loves them because they are such good layers. I think I've got a good mix there, strong layers with good size for butchering later.
