Newer projection sets in the same price range now have 9" tubes and resolve the full 1920x1080(2,073,600 pixels). Mine has 7" project tubes and resolves around 1400x1080(1,512,000). Upgrading wouldn't give me quite the same bang-for-the-buck image improvement as going from 852x480(408,960) or 1024x768(786,432).
