I was recently in the market for a rack for my adults and had seriously considered a Vision CB-70 rack. It sells for a good price and would hold all my adults in one space.
I decided against it, though, and went with one from Reptile Basics. The problem with the Vision rack, for me, was the height. I am short and having an almost 6ft rack would mean I'd need a chair or ladder to get to the top tub easily. The RB racks come in sets of 3, which is easier for me.
There are lots of choices out there and I think everyone has different requirements. Find a rack that you like and go with it! :sunny:
