I personally think you should figure out your situation there before getting anything else.
It sounds like you have some fixing to do on your beardy enclosure. I would fix that first bc they are presently living. As well as concentrate on bringing the animals
In the house. Let's face it Garages are not the right place for exotics. You already had one escape that lead to the animals death. Luckily you found him but what would have happened if he had happened to make it outside or into a neighbors house? We've already got a ton of bad press, laws trying to be passed etc. do we need anymore? I'm not trying to be a jerk. But if you have beardies in the garage that have to have lamps on 24/7 (they need a day/night cycle) so they don't get too cold. I firmly beleive their welfare should come first at this point. Spend the money on cold proofing their enclosure and make sure they are getting the very very very best before you look into customizing a ball enclosure and getting a new ball. Both won't be cheap and at the present the beardies are living and sadly the ball isn't. Priorities!
