Just in case anyones in the market for a nice portable projector, Misco has a Sony VPL-EX1 for only £400 at the moment. Its a XGA and seems to be about 300 quid less than anywhere else. Mine even has a 3 year education warranty upgrade free on it. Only 2000 hours bulb life though which is a bummer
I just bought 4 and really begrudge giving them out as they look, as most Sony stuff does, gorgeous.
Note: I am not and have never been an employee of Misco and to be honest don't like them too much.
