If you watch numerous sources, the iScan Ultra should be high on your to-buy list. It offers switching, video adjustments, controls, and a 480p output in two forms of analog (RGB, component) and DVI. It also mates well with smaller fixed-pixel front projectors having displays that are 1024x768 or less. Its only drawback is that it doesn't offer scaling for different types of fixed-pixel displays or CRT front projectors (for this you should look to iScan's competition like Focus Enhancements).
