Your "what kind of monitor to get" question leads me to the following conclusions:

1. You have no idea what you might be getting yourself into.
2. You have done no research whatsoever, you haven't even looked at a lot of pictures to see what appeals to you.
3. You don't know if you want a small one, a medium sized one, or a large one. Or even a super large one.

The first things to ask yourself are these questions:

1. Do I have a lot of space available? Even small species require large environments comparable to their size. This is a ball python website but monitors do not fall into the same kind of "easy to take care of" category that ball pythons do.
2. Do I have a lot of money? Monitors are not the "feed once or twice a week" type of pet. You will spend many times the amount of money needed to feed a ball python.
3. Do I know how to establish trust with aggressive reptiles? A lot of reptiles can earn your trust rather quickly; but monitors are intelligent and inquisitive and it takes a lot of patience to earn their trust completely. It can (it has for me) take over a year to establish the trust of a wary specimen.
4. Am I aware that "care sheets" of any value simply do not exist? That's right. I've looked at a LOT of care sheets for monitor lizards, and am yet to find a good one. Save yourself the time and explore other options for gaining information.

Don't just run out there, buy a baby WC exanthematicus, and kill it slowly.
