When I used to shop for them, Officeworks was always pretty cheap. They seem to be still competitive now.
Staticice shows some small tech vendors have good prices, as long as I know exactly which model I'm after (but I don't nowadays).
Any other places I should look? Do Amazon, or any of those sites, deliver projectors to Oz cheap enough to make it worth risking no local warranty?
Personally I'm after a 1080p one for blu-rays and PC gaming in a dark or near dark room (will consider 720p or 1280x800 if cheap enough). 3D might be nice but is no big deal, I never use it on the TV.
I've been looking aswell, there are a number on ebay with 1280x800 resolution without 3d relatively cheap and have LED bulbs which last allot longer than conventional
