I noticed your other thread. I think the experienced monitor/tegu people here would agree if the extent of your reptile keeping ends at Ball Pythons for 1 year, these giant lizards would not be a great next step. To start, you should consider whether or not you have the space and funds for an 8 foot x 4 foot x 4 foot enclosure and whether or not you area ready to take on an angry dinosaur if its having a bad day.
