So I was needing at LEAST a milligram scale and hunting around everything is really expensive and not really all that accurate OR precise... Even though I don't usually do it, I wound up doing a general google search (I NEVER do a general google search when shopping!) And found a method of building a really nice one myself with an old discarded galvanometer (NO ONE uses these anymore for their original purpose! It's all about the multimeters!) and a bunch of electronics parts that can be gotten from most any small electronics shop for all told around 100 bucks. Add a bit more to the price and I can drastically improve the max load. Add yet more and I can give it all a nice finish so it even looks nice. All told... It'd cost well under the minimum $200 for even a "milligram" scale that's only remotely accurate within 5mg and even then... I wouldn't trust it to within more than 10mg. And would be precise and accurate to the microgram, with a most marvelous ability to sense real time load changes without getting "stuck". Perfect for my needs.
Unfortunately the website I found this on is an archive and the reported software to go with it is not available on the archive site. The original site died back in '08. I found a facebook group for the society that ran the original site, and have applied to join the group... Hopefully I can get access to what I need and start getting parts. The software may need some alterations even should I get a hold of it because the hardware originally used might no longer be available.
