I'm between pedometers at the moment but the one I like and had (until the dog chomped it!) is the LifeStyle. Here in Canada, it was C$25. It does steps, miles, etc and has other functions but I used it mainly to see how close I could get to 10,000 steps perday.
If you get one, attach a ribbon to it and pin it to your waist as well as clipping it. They have a bad habit of falling off when you go to the bathroom.
Hope this helps. (Making note to self to buy another next time I go to town)
