I just bought a Casio Privia Pro PX-5S from Sweetwater last week. Even though it was an online purchase I had a dedicated salesman that walked me thru everything and did a complete follow up after it arrived. He even sent me links to some Casio groups which had all the vids I needed to get things rolling. It was one of the best online purchase experience I have had!

P.S. The Casio website has a user forum that is regularly monitored by Casio. They often post replies directly from Casio personal that is often unsolicited. I expected replies to my posts to be from users.......not Casio techs!! Kudos to Casio!!
