Do you have one of the new Macbook Pro machines with the SD Card slot? Perhaps you would be interested in testing out a bootable SD card. That's right, you can create a bootable start-up disc, but it's on an SD card instead of a disc. Macworld has created a great little video showing you how. You need a few things to get started though: A Macbook Pro with an SD card slot, Mac OS X install DVD, and also a fairly fast SD card with at least 8GB of storage on it.
