Looking at US pricing, I believe year 2008 would be a good time to get Full HD projector. Currently still using my 2 years old 720p DLP projector. It all depends on your sitting distance. If you sit around 1.5x of your screen width and above, you wouldn't see a difference between 720p and 1080p projector. You need to sit aroudn 1.2x to really see the difference. Also, source is another issue. If you primary watch DVD, then I don't see an advantage to upgrade now.
