The two best burners are Plextor and Lite-On. If the Lite-On was the same price as the Plextor, then I'd get the Lite-On. Right now I have two Lite-On opticals...a DVD-ROM and a CD burner. I've been waiting for speeds to go up and prices to go down on the DVD burners and they are really good right now.
Here's a Lite-On Dual Layer DVD burner for $54!

For about twice as much for $119, you can get the Plextor Dual-Layer burner:

If you've got the money, get the Plextor, or if you simply want to save the money, get the Lite-On. Both are great burners. I've used both and both have been equally stunning. They are the best because they burn the best for making movie or game "backups". Doing "backups" is the most demanding thing you can ask a burner to do and I see few (if any) beating these guys.
One thing you can save money on that is definitely not needed. Don't buy SATA optical drives. Your wasting your money if you do that. Just stick to IDE drives...opticals that is. SATA hard drives might net you some performance but I digress.
