About a dozen readers wrote in with suggestions for an accurate body
scale, one that would give you a consistent reading within less than
a pound, even if you say, stepped off the scale and back on again.
Four people recommended the Tanita digital scales as providing
repeatable readings to within 1/5 of a pound. The Tanita UM-015 was
selling at Costco for $25, which is a good deal. Three people
recommended the Soehnle line from Germany. (Thanks to Blake
Sobiloff, Bill, Ger, Dan Dubnov, John Biddle, Myles Kelvin, Peter
van Impelen, Phil Mann.) But before you head to the store, read this
note:

"I've got a low-end digital scale and in an attempt to fake quality,
the manufacturer has built in artificial repeatability. If a
subsequent weighing is within about 2 lbs. of the preceding weighing
then the previously reported weight is re-displayed -- regardless of
how much time has passed. So a person loosing a steady .1 lbs a week
will show the same weight for 14 days and then suddenly loose two
pounds. I find that in order to get an accurate re-measure I have to
step on the scale holding a weight between each actual measurement.
Just a word of warning about using repeatability as an indicator of
quality." -- Ryan Brase

With that warning in mind the scale below may be a best choice. Also,
a scale for very large folks.

A physicians' balance beam scale is consistently accurate. We've had
one now for at least 25 years; its accuracy has remained constant
through many moves, changes in humidity, and so forth. Measurement is
in 1/4 pounds, which is good enough. There is a readjustment knob if
you think there is an error when changing the scale's placement. If
only my weight and height had remained so constant....

-- Martha Robinson

If you want consistency and accuracy in a body scale, I strongly
suggest an old-fashioned balance beam scale. Even a cheap one
(<$200) will do a better job than most expensive electronic scales.
Also, they are kind of fun to use, they have an eye level display,
and the batteries never run out.

I'm a big dude so most scales don't even cover my weight.
Consequently I had to think different to get a decent scale. I found
this digital postage scale. It reads up to 400lbs in half pound
increments, has a remote, mountable readout auto tare (useful when
weighing the dog). It isn't particularly pretty but being in the top
percentile in weight and height has certain drawbacks and requires
special tools.
