I am in the tank side as well. I like to enjoy the snake and I find that easiest with a glass tank, even if I cover three of the sides - Tubs are easier to manage, but one can make a tank meet the same needs for the snake, they've just gotta work a bit harder.

I mix 50-50 Aspen and coconut husk, and the sides of the tank have Sphagnum. I don't need to wet the sphagnum until he's in shed, usually a misting does the trick. Right now it's winter in MN so the air is REALLY dry and it's hard to keep it consistant. If you keep having trouble, you can buy (or make) a little repti-fogger to do the work for you.
