At my shop I image 400-500 laptops and handfull of desktops each August - we use the Mac's ability to boot up in target mode, making it a dumb hard drive, then connect it to another Mac with the source OS on it, then we use an application called Carbon Copy Cloner to copy that source OS, bit for bit, to the target. We get a bank of ten or fifteen of these pairs running at a time, and we march through things pretty swiftly.

There is also a feature of OS X Server called Net Boot that allows you to put an image on a server, and then get the target Macs to pull that image over ethernet - we haven't used it because it bogs down our network for other things. But it's an option too.
