"The latest piece of technology to see a significant drop in prices has been the 2.5" size hard drives. You can easily pick up a SATA 60 GB drive for around $50. If you want to use one of these drives as an external hard drive, you will need a proper enclosure. Zonet has come out with enclosure that is both utilitarian and sexy at the same time. The Zonet ZNS8021 USB 2.0 Leather SATA Enclosure provides a solidly constructed protective case that is also pretty nice to look at. In addition, it is lightweight and compact."
