Welcome to the forums and to the enjoyment of ball pythons.
MootWorm is correct in the fact that BPs are addictive and you most likley will not stop at just one. There are always tons of people on this site that are extremley helpful with any questions you have on the care and maintnance of the snakes.
I have switched to tubs and racks because they do not take up as much room as the tanks do, they are easier to maintain and the snakes do better in them.
This is one of the best tub set ups I have seen. It gives a good step by step look at how to set everything up.
