Bigshop: Viewsonic PJ258D Projector With iPod Connectivity - $999 +2.7% cashback
PLUS 2.7% cashback!!
It's the cheapest price for this unit that I could find with a quick look around.
Deals Direct are after $1399 for it, plus $30 postage, so Bigshop seem to have quite a good price for it.
Offer valid until June 3rd 2008.
