I just wanted to add this suggestion, if anyone were interested. Since a lot of people are having trouble finding safe grids and the ones that are safe are more expensive check your local Craigslist. Some keywords they are typically sold under:

Wire Cubes
Wire Cube Shelving
Cubes
Storage cubes
Wire storage

Just be sure to look carefully at the photographs (if posted) to make sure they are the appropriate size. People sell them for little to nothing most of the time. Usually they are sold by people who used them in their kids' rooms and they've grown out of them or kids who used them in their college dorm.
