I love Old Will Knot scales, they've got a great selection. Here is the one I use...

I've got a few other scales at home that were given to me by a friend. He used to be a polceman and before he retired he cleaned out their evidence room and got rid of all the old stuff they didn't need to hold for court anymore, he had quite a number of gram scales to pass around...

He never mentioned following anybody home from WalMart, but knowing him you never know...

I also got a number of hemostats from him to use for feeding tongs. Funny thing about these was that they were all burnt at the tips... Hmmmm
