Weigh scales

I sold my mechanical Ruggles weigh scales and now am trying some
digital automotive racing scales that are just a little more expensive.
The scales I found are actually less expensive than normal racing
scales but the real advantage is that they can be sold individually
rather than a set of four. For my purposes I only need two (use
bathroom scale on front wheel) and that brings the price down to about
$500 for two digital scales compared to $310 for the
mechanical Ruggles scale set. I tested the accuracy of the new digital
scales and they seem to be accurate to the nearest pound thats quite
better than Ruggles. You can see the scales at

Another place

also sells them, but when they found out I was going to use them for
aircraft, they went bezerk and would not sell them to me but insisted
that I purchase more expensive ones. I tried to explain that I can
possibly calibrate the cheaper ones (just like you calibrate a compass
with a compass correction chart) but they were so caught up in
superlatives and safety slogans they would not listen.

Any two of you can get together and purchase a whole set for about $900
and split it. Thats only about $450 for digital aircraft scale set
(plus one good bathroom scale).
