Here's the humid hide that I did.
It's just cheap-o tupperware available at publix or the dollar store or wherever. You can use any old container lying around the house. I have a soldering wand for my tubs, and I just used that to carve out the top. If you dont have a soldering wand, you can just use scissors to cut out a hole, and use an emory board (nail file) to smooth out the edges.
It's not at all difficult. As for the bed a beast, that stuff is a pain. You have to make a ton of it and then find a way to store it. It takes ages to dry out enough to use it, and if you feed in the tank it could be digested by the snake. Just my opinion.
