What is the best moisture and test weight tester?

I have a Dickey John GAC 2100 Agri only does 8 crops in memory, more than that and you need to get out your screw driver and put it into edit mode and enter in new constants. It is an incredibly flexible machine and will test almost any grain. the Comercial version has more memory to do many grains but costs an additional $1200

good for moisture but not legal for trade on test weight. it seem...
