Get a trainer. Get a trainer. Get a trainer.
As in a trainer plane. And a trainer person to teach you to fly.
Historical planes are fine once you've got some experience. Same with aerobatic planes. But you need to know how to takeoff and land every time, and learn to orient a plane that you're not in. It's totally different from real planes and video games where you're in cockpit.
Plus, you don't know how much you'll really fly. Buy a trainer and radio and you'll have $600 or so invested - a lot less than all the other stuff in this thread. You can use a lot of your gear with your next plane. If you stick with it, great. If not, you're out relatively little. If you crash, you're out relatively little. An aerobat or warbird can come later, if you really enjoy it.
Also, I'd recommend going with electric motors. Much nicer than glow fuel. I never fly my glow fuel trainer anymore -- it's too much of a pain in the bellybutton to get it started and keep it running.
