Elliott,  I still have my Shure balance bar and a little kit of "Last" and the full Zerostat set in a walnut base with lid!  Oh and a very old Audio Technica record weight.  But, no TT......

The Shure isn't accurate.

No, but the pot shops here in Seattle sure are. So what I do, buy a gram, put the green bud on the Shure, zero it out at 1g. Transfer weed to bowl. Drop the stylus, adjust VTF, light the bowl. Very important these be done in that order. You can trust me on that. Barts will vouch for me on that. He keeps his Zerostat in a walnut case with a lid.
