Well, my recommendation is to get one cheap.
DVD Burners from Pricewatch
If you get a DVD burner, get DVD+RW or DVD+/-RW.
As you can see from the link, these can be had so cheaply that if you DO fry it, you can replace it for another $45. At that price, buy one and three spares, and you still won't pay as much as going to Comp*USA or a similar retailer for a "quality" DVD burner (and yes, all DVD burners read and burn CDR/CDRWs, too).
The first dozen or so hits are for external enclosures, which I also recommend. If it goes "bamf", you just take apart the box and put another one in without opening up your computer. More importantly, you can share the same burner with multiple machines (including your notebook), and there's no question about whether you're putting the last straw on the power supply's capacity, or that extra calorie of heat that will do it in.
While I'm on the external drive rant, be sure and get yourself an external USB2 or firewire hard disk while you're at it, and backup your computer's hard disk at least weekly, or whenever you do some significant work. This is faster and more convenient than DVD or CDR media, so you will actually do it.
