Rock Ideas for Cichlid Tank?

Hey All - Just got my 55 Gallon Tank setup for African Cichlids and contemplating rock ideas. Anyone have recommendations/links they could share? I hear Seiryu Aquarium Rock is the best bet but can I find that local? Or should I find it online? I live in MN so just not sure where to look. Or should I go with a fake rock? Maybe a mixture of both?
