Can't help with a tank personally because I don't use them for my balls, but I can help you with a tub setup:
Sterilite Tubs from Walmart, $5-$10: 6-15qt for hatchlings (I use 28qt for the littles and it works for me), 34-41 qt for adults.
Binder Clips ($2 Walmart) or Luggage Straps so he can't get out.
UTH (I get mine on eBay for $16.75 -20 gallon sized- with free ship, but they're in petstores too). I use the 20 gallon sized ones for my 28-34 quarts.
Dimmer ($10 at Home Depot) for the UTH so it doesn't get too hot or a good thermostat (easily $70+)
Heat Tape to attatch the UTH to the tub as it might not stick by itself (varies by price, I think I paid ~$10 for my roll).
Temp Gun to check hot/cold spots (~$30, I got mine at Lowes)
Thermometer for ambient humidity/temps ($8 at Walmart, Acurite brand). I like ~50% ambient humidity and ~90-92 hot side surface temps and ~80 for cold surface temps
Cage decor, hides, water bowl, etc of your choice. Paper towel substrate for me.
This is just what I do/use personally: everyone does their own thing which you'll see when more people post.
