I had very good luck with an Omron pedometer before I got a Fitbit. It counted my steps accurately whether I wore it on my bra, pocket, or even my purse. I wore it all day long.
I shoot for 10,000 steps. I walk my son to preschool every morning and then go for a walk. By 9:00 I've usually racked up 7,000 steps and 3.5 miles. I get to 10,000 just by going to pick him up. I walk way more though, to the grocery store, around the house, doing laundry, going to work etc, I finish the day around 15,000 or more.
Go with an Omron, you can find them at sporting goods stores, this is the one I used.
