I'm currently using the Reptile Basics hatchling rack, which has back heat, and isn't cutting it for me. I'm looking for an enclosed hatchling rack (prefer iris tubs but sterilite is fine) that has BELLY heat. I wasn't expecting to need to buy another hatchling rack right now, so I'd prefer smaller/cheaper models. I would just rewire my current rack, but the shelves are interlocked and do not allow for easily adding belly heat.
