If you've got a home theater setup already, PodBoy's right that you probably could get set up well without enlisting an installer. You could pull the Proceed and and slide in the 990, then add the DVI cabling - the 990's DVI switching needs very little tweaking (in fact, the 990 itself just needs to be told to use the DVI switching and it's done). You'd want to re-calibrate your InFocus once you had everything hooked up, but that process would be no different than what you've probably done previously with the InFocus's component input.
