Pros: Quiet, burns well, reads well
Cons: None really
I purchased the LiteOn when building my sigrig, and from there I've never had any trouble. The drive is quiet, burns disks well, and reads disks well too.
In addition to this, my drive came with a copy of Nero 8 Essentials, some of the best disk burning software I've used in a while.
I could not recommend this drive more. It's cheap, efficient and does the job well.
