I'm one of those crazy weigh every day people. I don't like surprises, and I weigh in and log daily and it motivates me and helps me stay on par. A scale doesn't have to be so technical that it is able to launch people into space. The technology it needs is that it just needs to be accurate. You can get such a scale for about 20.00 just about anywhere. I use a digital scale that weighs in half pound increments.
