He's just now getting them manufactured.
The stands he's going to use are different than the ones in the pic, too. The new ones are more like garage shelving style, so it's easier to adjust the spacing of the trays.
Not sure about pricing yet. Still working all of that out. Should be under 100$ a tray.
If anyone's from CA, I am pretty sure they are going to get a booth at the Cannabis Cup in SF in June.
