Creating a disc image for multiple installs

Just kind of looking for a "best practices" sort of guide, since I found a ton of them searching.

I want to develop a hard drive image on CD for each model of computer we have at work (we have volume licenses, so no problem with a single image for every machine) . This way, I save tons of time by not having to install windows, then install drivers, then install software, then install updates, etc.

Is there a recommended procedure you MS professionals use for doing this? Or a particular toolkit that's recommended (I know you can build an unattended like this with tools inside Windows, but like every mousetrap, I'm sure someone's built a better one by now)?
