I bought one a few months ago, then got rid of all my CD drives except for one big 5.25" internal CD/DVD drive with USB adaptor that I take out of the closet whenever I get a new CD that I may need in future. I convert the CD to an ISO, load the ISO onto the Zalman, then put the drive and CD in the closet.
