It's actually really inexpensive for what it does. And although it seems really complicated once you have built it once in creative its not that difficult to build in survival with a little pre build planning. By the time you build two single cell snail farms you could have one of these.
Naa, only takes like 15mins from start to finish, plus the resources are far cheaper in comparison. But sadly I have a 5 building snail system already or I probably would have tried to set this thing up. Maybe if we move locations or start a new world and I will give it a go.
