Hi Gary and Stefan,

I had assumed Gary was talking about scales for measuring
meteorite mass, but perhaps Stefan's interpretation is
correct and Gary was looking for photo orientation cubes
(or something similar).

However, if mass scale is what you meant, there are two
main issues that affect cost: accuracy and dynamic range.
I use an Acculab V-200 digital scale that reads out to
0.01 grams and has a mass limit of 200 grams. So a dynamic
range of 20000, or a little more than 14 bits. This is
actually rather good for a scale that is quite modestly
priced.

If you need to go heavier than 200 grams, you'll probably
be satisfied with 0.1-gram accuracy. I'm sure someone
out there on the list can recommend a good digital scale
than can weigh up to a couple kilos or more (Acculab
makes these as well).
