By your past posts it looks like you are a newer pilot, so a big heli really isn't the best choice, there is lots more to go wrong and these things are dangerous and can kill a person. I know that horizon hobby (specifically blade) makes some beginner helis that are well within your price range, and I'm sure that they will help you learn a lot. You can probably convert one of those smaller helis into a scale one in the future if you really want, just something to think about.
