The bus is best, most courier companies and the post office have size and weight limits lower then the Greyhound. Also with the Greyhound once something is loaded on the bus it stays there until it gets to it's destination, unless they change busses which doesn't happen unless you need to get on a ferry or something. If the set goes over the weight limit the chassis and or speaker can be removed and packaged seperately, every few consoles go over 100 pounds fortunately but this will solve that issue for the ones that do.
