Protecting Memory Sticks

I have acquired a number of memory sticks over the years. I just read an article about how to password protect/secure such a device for sensitive or personal data. So I had a go at downloading the free software called Cryptainer LE and after a fair amount of messing around managed to create a 25MB secure partition on one of them which worked. As the article said this is fiddly and not something you would easily explain to a non-specialist like me (euphemism for someone who is most likely to carry sensitive data on a USB stick). So I'm thinking about buying a USB with security built-in such as the Kingston DataTraveler Locker. This could be a useful thing to hand out to a number of work colleagues too - I routinely (every quarter) create secure CDs for disaster recovery purposes and this might be a better solution. I wonder if anyone has any other experiences to share on how best to go about this?
