Crave shares quite a good deal they found: a Western Digital Passport 160gb drive for $88.39 USD-if you pay with PayPal and select their lowest-end shipping option, which I assume only works in the US.

I love these drives. They're tiny and fit nicely in my bag with all my other gear. Just a drive and a small USB cable.

When I had to send my work laptop back into the office recently for repair, I still needed access to my data. I bought one of these drives, plugged it into my laptop, and copied the data I needed. I moved the data to another machine I have here and continued working.
