If you can't afford a glass tank, a bin of the same size with a locking lid will work too. Drill enough holes in the top or the sides so that air can circulate, but humidity is retained. With a bin, humidity is easier to manage, it just doesn't look as nice. If your new beep is a baby, you can opt for a smaller size tank or bin, as long as the temp/humidity/hide needs are met.
