Man this is such a loaded question I'm fighting to keep my words to a minimum here. I would start with this...

Then if you like it keep upgrading to more and more involved aircraft. That's what I'd do. Start with toys. If you enjoy the toys, then you can get the four channel or higher RC planes. It will save you lots of money to do it this way, especially if you're not sure you'll stick with it...used rc stuff does not sell for much.

P.S. The only problem with the cheaper "toy" electric planes is that any wind above 5 mph and you can't fly. The bigger RC planes can fly in up to 30 mph winds (or more if you're really good and have a powerful engine).
