You don't "own monitors to get experience". You own monitors because you have a passion and a respect for them. Monitors are a completely different class of reptile, with completely different care needs than any other reptile money can by.
I apologize for coming off harsh, I'm mildly fed up with people owning monitors for the wrong reasons and seeing so many dead/in crap shape because of poor husbandry. If you actually have a passion/interest in monitors. You may way to stay away from savannah monitors. They need lots of room in a custom built enclosure, high temps and humidity, and a strict insect diet. All the videos of them in any sort of an aquarium are wrong. All the videos of feeding mice, are wrong. A sav kept properly should be near adult size at 1 year of age.
If you are serious into keeping monitors, try to look at something like an ackie. They are much more forgiving and are a much better starter monitor due to size/temperament/husbandry requirements etc.
You need to do a lot of reading, researching, and studying of monitors and reading from proper monitor keepers before you get ready to get into this realm. No amount of ball python, boa, and bearded dragon keeping can prepare you for a varanid.
