Congrats and you will find boas are the greatest you can go without a "giant" snake. I used to use aquariums but I got tired of it. Cleaning is harder and they are harder to heat and keep humidity up. Now I just use tubs, cheap and easy to clean. Upgrade as they go. My male was born 4-12-06 and is on 2 rat pups about every 5-7 days and lives in an 18 qt. tub with room to grow. I like the idea of providing your boas with the most room you can. I really like the idea of custom cages. I saw a few boas in 6' by 30" cages and it looked perfect for even the largest boas.

Good luck and feel free to ask us more questions!
