Hey man, here are three links to DVD-RW's on Newegg, any one of these would fit your needs and will come with the software needed
Samsung DVD-RW,
Lite-On DVD-RW, and
Asus DVD-RW.
All of them are similarly spec'ed and roughly the same pirce with the Asus being a bit more expencive. One thing you will need to watch is if you have enough free connections for them as the Samsung and Asus drives are SATA interfaces, and the Lite-On is IDE.
I hope that helps
