Shortly after sending the MMC application we received a notice from the ag department that we could only use a "Legal for Trade" Certified scale.

The $300 scale, while nice, weighs exactly the same as our crappy $50 scale. I had checked it with calibration weights before we got the notice and it was dead on.

The new $300 scale is dead on too, but it settles much faster.

In addition to buying the "legal for trade" scale, you also have to apply to the state for a license to operate that scale. They will come and check it once a year so you have to have an approved scale.
