I would say a good quality outfit with a 5wt - 9ft - Medium Action fly rod, WF-5-F fly line, and any decent fly reel. You should plan on spending at least $100 to get a quality system that will make it easier to learn how to cast.
Generally, you can't learn to fly fish by ONLY watching others. You will need some instruction even if its just a little reading. I assume that when you joined this forum, you took advantage of the free eBook "Excerpts from Cast Like A Pro" by Doug Macnair. This is a great place to start for learning to fly cast.
