make a 1-step recovery cd?

Anyone have experience making a bootable,scripted CD that will automatically blow in a complete image of a prepared configuration? Either a ghost-type image, or something that resembles the system restore cd you often see with laptops and big-name desktops? I want to insert the thing, say "go", and be done with it. I'm reconfiguring systems for reuse in an enterprise where they get used for 6-12 weeks at a time and then need to be put back to original condition in a hurry.
