Hang onto your money untill this 2.4 ghz thing gets more established in the next year or so. I don't know if you know how to fly yet but buying a big fancy radio in the front end that you have no idea how to operate seems like jumping the gun to me. You need to walk before you can run. Throwing a bunch of money at this hobby will not speed up the learning process, it will just confuse the situation and make it worse.
