I have this little shop grinder out in my tool shed that works very nicely for shredding my old cd's, rendering them to dust in 10 to 15 seconds. I can do stacks at a time I'm sure, but I've never truly had the need to do so. I bet my sledgehammer would render them down almost as quickly. Why would we need a hi-tech gadget to destroy them when simple things work?

Oh - and a bit off topic - all those lil freaking aohell cd's that get sent out make a nice prism wall art piece in one of my bathrooms. I see them and get inspired : cool :
