Good big lizard to start off with

You could try an Ackie, they stay pretty small


I like my Dubstep to go Wop Wop Wop Wop

No matter how many times people like to recommend these, I almost never see them for sale. Whenever they are available, they're utterly unaffordable.

I would say 12 x 6 for a tegu would be sufficient; but bigger is always better.

That's outrageous. Only a zoo could provide an enclosure like that, or that would require an outdoor pen, if the weather was agreeable. It'd be one thing if the tegu was always locked in it's enclosure, but odds are people would getting a tegu so they can take them out and handle them all the time.
