I got it at walmart, over near the camera/electronics section. I don't remember what it was called, but it was only about $3-4, and was the largest thing I could find that I didn't mind carrying on my belt all the time. <img src="/images/graemlins/smile.gif" alt="" />

It's not on the website, but next time I go to walmart, I'll make sure to get the name and brand for you
