reptilebasics.com has everything that you would need. there's other brands/dealers on t stats but the ve ones are good. if you are building your own rack i'd highly recommend looking at pvc and not wood. i've been down that path and pvc is the way to go for sure. check you local homedepot not all of them carry the 4x8 sheets but its worth the time finding the ones that do. IMO the econo line racks from animal plastics are a deal for the price. just have to compare the value of your time and materials vs the price difference for store bought racks. good luck
