You could probably built a wooden frame cage with screen around it (as long as the edges aren't sharp) much cheaper than the cost of that cage. That's a lot of money to spend on something that will probably be hard to clean. Is the whole bottom level open or is the section under the nesting box closed off? It's hard to tell from the photo. If the bottom is open or made of wood, you'd still need a protective surface to protect your floor. Plus, if the wood is treated, there could be a risk to your pigs if they chew on it.
