My vote goes to Animal Plastics. Just got my 3 T10s in and I love them. They are sturdy and I like how the base is flat. I have a Constrictors NW cage too but it is much thinner and I personally am probably going to sell it. They are good too but I like the feel of the Ap cages more. They are heavier but very sturdy plus I went for the LED lighting, shelves, locks and flexwatt all installed so it was pretty much just plug and play. Check out the AP T10s. Those should last a few years and if your girl gets big, you can always upgrade later. I'll probably go for some T25s in a couple years. Definitely get the shelving though as that adds a lot more space and your boas will love to stretch out and perch up there lol.
