I prefer Ghost myself - 7GB restored in under 10 minutes with ease.
After that, Kix takes over to alter the SID and install any programs that may be missing from the restore image.
Like your own setup, completely unattended.
I do use ghost for some, just not my brother's stuff as each one runs different apps, so only need basebuild (with drivers), GPO does rest. Also, makes it a piece of cake to slpstream service pack without having to recreate ghosts.
Can't get your speed for build from DVD though, guess you're doing it from disk/network?
Ghost allows you to add service packs and various other updates to image files, as well as installing software.
However, you need the Corporate version to be able to pull that off.
As far as speed goes, yes it's network for under 10 minute restore times.
I do have a Tosh Satellite here though that can restore a 6.3GB image (compressed to 3.2GB using Ghost's own compression) in 12m 37s when run from a bootable DVD-R (Taiyo Yuden).
I've noticed that the newer Tosh's ain't so quick, but I put that down to the fact they use those wanky Matsushita drives these days.
