I bought the EKS doctor's scales from Argos before embarking on this, and made a huge mistake, first of all because they're not electronic so not precise enough, and secondly because the dial is way down there and I can't read the figures properly so twice the issue with precision!
I made a mistake, these ones were £16.99, that's another pound lost, lol.
What annoys me is that I have somewhere in my house one of the first BMI calc scales, a Tanita one, cost me £80 at the time, still works like a charm, has seen me through thick and thin (literally!)... can I find it? Take a guess. Story of my life!
