Ok Kuro....everyone is new and needs different degrees of help. Lets start with this. I too thought the bins were mean when I first started. But they are use to living in termite mounds....they like it like that. Really!!This would be a cheap cage and easy to maintain for you guys. Instead of a viv...they are more expensive...but make great show pieces.
You can get a 32 qt. long bin and that is great for an adult ball. Just line it with paper towels or newspaper. Now for the heating. If you get a bin a light will not work. You will need to get an under the tank heater for one side of the bin. This will need to be regulated by a thermostat. Thermostats can get a little pricey....but everything else is fairly cheap. Some ppl even use rheostats....I cannot tell you about those as I really don't understand them much. Ok...the under the tank heater goes on about 1/4 of the bin or the tank underneath it. You should set the bin on something were it can "breathe" underneath. An easy way to do this is just put a couple pieces of wood underneath each end. You can also get banna clips for the bin to lock the top down.....so the snake cannot push the top off.
Ok...now get yourself an acurite thermometer....Walmart or Lowes....$12-. It has a probe and will tell you the temp and the humidity. This is a great thermometer and very reliable.
As for feeding....feed in the enclosure.....they will not get enclosure agressive when you reach in when not feeding. This is like an old wise tale. They are much more comfortable and .....it is less mess and hassel. Also if you feed live be sure to watch until the mouse has been killed as they can attack your snake and do serious damage.
For the inside set up....as stated before use newspaper or papertowels. Get a couple of hides. One for the warm side and one for the cool side. Plus a big enough water bowl that he can soak in it if he so chooses.
Ok.....I think that is enough for now. Please feel free to ask any more questions you might have. Good luck!
