Professional install and calibration is a joke. I've had 3 projectors and was able to get everything set myself and looking great with just the price of a decent calibration disk. Find a calibration thread for your projector model, there are often several installers online who post their settings. Take those, apply them to your model, and use a calibration disk to fine tune the settings to your unique bulb and unit. It's easy and cheap. Plus what you consider a great picture is often different from what someone else conisders a great picture. You may like a slightly greener or redder picture, you installer may not. Picture, like sound, sound be based on your taste alone.
