My plan was to get my son one and that's it. I ordered his but it was a hatchling and had to grow a bit. By the time it was ready to ship, I had decided to get one for myself and had put down a deposit for him. We ended up getting them 4 days apart. Now I am looking at more, but I don't have the housing, so until that happens, two is where we'll stay. According to my wife, two is where we'll stay until my son moves out and then we'll have one!
