Personally, I love
blue-tongued skinks. In my experience, they're not as stinky as bearded dragons, and they are slightly more forgiving in terms of husbandry and diet than most other lizards. They are docile, not as "hyperactive" as beardies and "durable" for handling.
One thing it is debatable if they require UVB lighting or not. My personal opinion is that with proper housing, heating (thermal gradient) and a well-rounded, vitamin-fortified diet, they don't.
Case. in point. "Baby Sinclair" raised from day 1 without no UVB and no access to sunlight. No symptoms of MBD or other deficiencies or maladies.
