I've not hear dof them either. However
http://www.tirerack.com/tires/index.jsp I have. Many folks report that they are great to deal with. Prices are pretty good too.
Keep in mind that when you get some from a local shop, mounting and balancing is generally included in the price. Not only do you have to pay extra to get your internet tires mounted and balanced, but you also have to pay shipping. Might be worth your time to add up and make sure ordering online is your best deal.
Is there any local info on the "battle" that happened in your area? My great great grandpa is supposed to have been in it (rebel). Always thought it would be neat to see some documentation of it though.
