I truly can endorse
Thomann Musicstore in Germany. Be sure to select your native language! Folks are friendly, reply to your e-mail within a day, are knowledgeable and have ample stock. During the process of buying the digital piano, I changed my mind and ordered another type, which was no problem at all. When phoning Thomann, you can be sure to get somebody who speaks your language (German, English, Dutch and so on) which is a relief since not all musical terms or expressions are known to me in either English or German.
Shipment is standard 8 euros and is done by a local freighter. I mean, if I drive to the next big city in my neighborhood, I'd spend more on gas and probably have to rent a car to haul the pretty big box back home. Due to Christmas time, it took a little bit longer than expected but still very reasonable: something like a week.
