Amazon "accidentally" had a sale on them for previous customers for less than that... a bunch of people bought multiple units and listed them. They might be harder to find on fleabay now. I know of at least one guy who contacted me about warrantying his ebay MS8, and I couldn't help him - had to send him to JBL, who didn't want to help him either.
My price isn't something I can list publicly, but we have a great deal on MS-8, especially if you are getting something else from us.
