I Have the W1070, and I am VERY happy with the performance for the price. Plus it does 3d! You do have to get the glasses separately however.
Before you buy a projector, use the calculator over at projectorcentral to make sure it will work for you room/screen size, distance.
Maybe I'm not the typical buyer but the bump up from 720p to 1080p is very visible to my eyes. The way ebay sellers try to market their 854 x 560 projector as "1080p" gets on my nerves!
