I agree on the wall shelf. The target pro shelf model is a little bit larger and I believe large enough. If not you can get another board of some type and then reduce using cones.
If you do not use a wall shelf then use a short floor rack. The Solid Steel 2 shelf racks are wide enough plus the lower hight gives you more stability.
