My very first pedometer was an Omron. I loved it!!! It was so accurate. There are a lot of really cheap pedometers that add tons of steps you never took. I needed it to be as accurate as possible so this was amazing. I have used several different ones and my latest is the Alvita Ultimate Pedometer. It runs around $20. You can get it at Walmart, Walgreens, Target, Omron site, Academy, etc..
Here is some detailed info on it:
