Buying a new DVD ROM - Suggestions?

I just put in a DVD ROM that was laying around at a friends house. I wanted to use it for encoding and found out it is only 12x!! What a joke. I don’t have a lot of money but am anxious to put in a second drive so I don’t have to switch discs. Any suggestions?

New DVD Burners cost about the same as DVD-ROMs now, plus you get a backup burner.
