These come with full warrantees, and are out of several authorized distributors. I don't think RTI want's internet sales as the drop the value of the product, I was told this much at CEDIA. If you are worried look at etronix they are in Indiana, go to RTI's site [Link: rticorp.com]
do you see etronix there?
Yes RTI may put a stop to the sales, all I can say is get them while you can.
