This Omron pedometer does a fine job for very little money.  I have one of the more expensive models and bought this for a niece, who does not want it.  I kept it and tried it against my more expensive one and it seems to be right on.  It is small, lightweight, and I love the fact that it has a small lid that covers the buttons.  The more expensive one does not have a lid and the buttons get bumped by accident a lot.  This less expensive one did not come with a strap but did come with the batter included.  Would buy again.
