Well,
Coworker @ I tested DBAN today, and it worked great, took about 15 minutes to do the Quick Format on a 8 gig drive. Coworker told me that computer wouldn't boot w/o an OS CD. As we get more boxes, I believe the plan is to try the other options to get an idea of length of time to run the app and find which option to use for our purposes.
