Welcome to the hobby.

Before you spend any money, I would recommend checking out any local clubs near you.
Here is a link where you can find clubs that are close to you: http://www.modelaircraft.org/clubsearch.aspx .
It there is a club within reasonable distance, i would call the club and see if you can check it out.
Many clubs will take you out and buddy box on a club trainer for a couple times without having to join the club.
That way you can find out if it is for you or not.
If it is something you like, I would join the club. Although it will be a hit on the $100.00, you will get priceless information and help.
They will also be able to help you find a good plane cheaply.
If they have a club trainer plane, you can learn how to fly and find out what kind of planes you want to use (glow, gas, or electric) before you waste money on something that does not work for you.

Although a warplane looks fun, it is a recipe for disaster for a first plane.
Get some information and recommendations from your local club. It will make getting into the hobby much easier and cheaper.
If your not into clubs, I still recommend joining. You can always drop out once you have learned what you need to learn.
You can go out and find a little ARF trainer plane and learn how to fly yourself, but it is a long and expensive process. If you try to learn yourself, you are almost guaranteed, to crash and destroy a plane or two.

I hope you have success and enjoy the hobby.
