Welcome to BPNet, Mike. We have the 8 tub 15 qt rack from Reptile Basics and we couldn't be more pleased. Easy as pie to maintain heat and humidity in, the tubs slide easily, the pins in front of each tub are a nice touch and I love that he uses Iris tubs (my personal favorite tub manufacturer). A perfect small tub rack setup for the younger ball pythons. We'll definitely be looking to buy more racks from Rich down the road.
