I bought an expensive pedometer and what would you know--a cheap screw came out so I can't clip it to my thinning belt. Anyone have some recs on a cheap pedometer--I guess they work as well.

I need advice too. Has anybody a good, cheap, reliable pedometer to recommend.
A friend at the gym showed me his that actually communicates with a satellite locating his position on the planet and calculates the distance walked/run....he recieved it as a gift and didn't know the price. But just IMAGINE how sky high it must have been. That seem a BIT over the top to me! :D

I haven't personally experimented with the reliability or validity of any kind of pedometer, but that's where research studies can help :D . Interpreted with caution, of course.
I looked at three recent North American studies (done by practically all the same researchers, so perhaps researcher bias?) and it seems that agreement was in favour of Kenz Lifecorder, New-Lifestyles NL-2000, and Yamax Digi-Walker SW-701 for being the most accurate in assessing actual number of steps (within 3%).
There were actually 14 models that were tested among the 3 studies I looked at -- all the pedometers worked best at a pace of 80+ m/min (they underestimated steps at 54 m or less/min and in those with gait disorders).
In other outcome measures, none of the pedometers fared too well on calculating the distance walked, and were least reliable in predicting the number of calories burned.
Just for interest, this was what I gathered (# of studies model was in, accuracy in assessing steps):
Accusplit Alliance 1510 (1, Underestimated)
Freestyle Pacer Pro (3, Underestimated)
Colorado on the Move (1, Underestimated)
Kenz Lifecorder (3)
New-Lifestyles NL-2000 (3)
Omron HJ-105 (2, Overestimated, Least accurate)
Oregon Scientific PE316CA (3, Overestimated)
Sportline 330 (3, Least accurate)
Sportline 345 (2, Underestimated)
Walk4Life LS 2525 (3, Overestimated)
Yamax Skeletone EM-180 (1, Underestimated)
Yamax Digi-Walker SW-200 (2)
Yamax Digi-Walker SW-701 (3)
Yamax Skeletone EM-180 (2)
I also stumbled upon info regarding Global Positioning System (GPS), or satellite positioning, technology in studying gait biomechanics -- very interesting!

I rode my car over several distances and then walked those distances and discovered that the pedometer was pretty accurate. Of course I could probably drive the different walks I do every day and I would know what the distance is but then again I'm a fan of gadgets and fashion!

scribbles,
Thanks for the info.
I think I'm opting for the Oregon Scientific...at $14.99 it seems a fair price.
Only worried about the 2 lithium R43 batteries that could get $$pricey$$ if they wear down too fast!
