Lowe's use to sell the plastic pegboard that is shown in the drawing but it has been discontinued. I am looking at another product Lowes sells back with the paneling. It is basicly a piece of paneling made out of PVC. It comes in a 4x8 sheet and cost about $32. You would have to drill all of the holes but it would work. I have a 4x4 piece of 1/4" plexiglass that I am thinking about drilling holes in but it would be pretty easy to crack it.
