DBAN is a good tool. I use it plus several others. I'm generally lazy thats why I use an 8lb sledge most of the time. Its some of the only physical activity that I get plus its a good release of frustrations.
cstone, shoot me a PM and we'll work out something. I have to wipe everything before they leave my shop so it'll take me a little time to get them ready. I know you wipe them also but I can't let them leave my shop with anything on them.
