Anything made well costs money. The manufacturer has to pay the bills for the tooling and leased factory space. The boxes are not from Walmart, and the racks are not made from inexpensive melamine. We are talking powder-coated metal square tubing and metal box rails and custom-made boxes..
Here are some reasons why they are good:
1. They are light in weight yet very strong.
2. They can get wet without compromising strength (unlike melamine), and they have a tough industrial coating.
3. They can be disassembled for transport and reassembled easily.
4. Interchangeable parts, including heat panels.
5. The heat panels use common Flexwatt, and the Flexwatt can be replaced easily if necessary.
6. Extremely space-efficient design allows for many cages.
7. The box sizes truly accomodate various animals. For example, the ball python tubs are roomy enough for larger ball pythons and aren't 28qt Rubbermaids.
8. They are on wheels.
9. The outlet strips for the heaters mount right on the rack.
10. A melamine rack that could hold adult boas would weigh a ton.
11. Lidless design makes cleaning easy.
12. Expandable - you can buy one level or 10.
This isn't to say there aren't other good racks out there, but for boas and pythons you don't have much choice if you want to rack them. Well, Roylance Racks, but they use a similar design.
I use racks from www.herpcages.com, but not for anything larger than a Cal king. If I were racking womas (I notice you have them) then FB or Roylance all the way when the womas are adults. Otherwise, use cages. Lots of great cage choices out there. Plastic rules for most boa/pythons IMO except when there isn't a size you need, then wood is the best.
Lets see, two Boaphile 4x2 cages shipped is about $460. What can you get from FB for that much? Check it out and see.
