I just built another rack that can house 8 adults, 12 juveniles, 16 hatchlings, or a combination of those and it cost me just over $100 including the heat tape. Actually, the heat tape alone cost more than half of the entire price. Building your own rack system allows you to make it hold the type of tubs you use and have it fill the space you have available. It also costs so much less, leaving you with some extra money to put towards herp supplies or even a new addition.
