Not all breeders are in it for money. Racks are used because there is no better way to meet the animals requirement and keep them happy and stress free. While translucent is nice for the keeper, it is not better for the animal, actually the opposite. I've made racks with the home depot stuff and they can work, still use them for some of my males, the quality rack systems on the market are 100 times better. I use ARS and yes they are expensive, but they work extremely well and they allow you to keep many animals in a small area meeting all their requirements perfectly resulting in very healthy stress free animals.
