out of stock BenQ W1090 2000 ANSI 1080P DLP Home Theatre Projector $849.15 + Delivery (Free with eBay Plus) @ Computer Alliance eBay
Solid price on what many say is a good first home theatre projector.
It's DLP and 'only' 1080p but should still wow most people, be good for movies, sport, and the occasional game session. Good quality 4K content is still not prolific so you're not missing too much immediately. Pair this with a high quality 1080p source and you'll have a solid home movie experience.
Review here for those that are interested.
I'm using a W1300 but this is tempting!
