i'd recommend breeding roaches if you want to keep any type of monitor. I breed them now for my geckos and its just giving me an extra excuse to get one.
I've seen a few in person including a very personable yellow male that was soooo cute. They are a very small monitor which makes them easy for the "apartment dweller" You can make a nice big cage that doesn't take up a whole room.
Pro exotics has a great care sheet on the little guys.
