Ken Brock made a training video for $35. Dan Lesli had a two tape edition for about $100, Bill Ortmayor had one for around 25 or $35. I like all of them. They supplement the training you will need from a CFI or BFI. There is a video you can down load from Lesli's web site called Introduction into gyros., Also ROC video. Rotorhead (here on the forum) has some really nice videos on his web site. All of it helps put a mental picture in your mind to help prepare you. These are still "aids" like the blackboard in school. You still need a teacher. Hope this helps.
