RR12,
This one issue alone is why you really should pass on picking up this collection.
If you have a concern for the well being of these snakes, try and arrange a rescue or pruchase from someone who can house them correctly.
I do risk management for a living, and in my opinion, this is to much of a risk to take on, even if the possible rewards are high. The possible downside out weighs the possible upside.
Good Luck with your choice.
