Explain please how a drill press is not secure.
1) flashy: not really
2) secure: definitely, no hard disk has ever been physically reconstructed that had holes in the platters. Short of a scanning electron microscope, you're not reconstructing that data
3) available: go to home depot
4) price: yes, more expensive than running dd if=/dev/random of=/dev/olddisk, but cheaper than an industrial-grade shredder and of course cheaper than any commercial "enterprise" data removing software. I think drill presses can be had for around $200.
