Hey Damo
Not really sure how come they are so cheap on ebay. I know what you mean, like perfectrun got them for $660. But than again, there is a site that i visit and they trade in Japanese yen.
www.takakaira.com
From memory there selling it for $500 (aust) something after the conversion from yen to aussie dollars. Our money is pretty strong at the moment compare to the yen.
I'm assuming that it comes with everything?!?!, don't quote me on it. But in the SACF2, i think it's just the unit, a stand and the cord/adaptor.
