Bently,

I think Flea Flicker and SG summed it up pretty well. Cabellas has quite a range of inexpensive rods and expensive rods to choose from. It's probably would be worth it to you to cast a few before buying though.

You could buy a rod with out trying it out, and it just doesn't cast well for you. You could be disappointed and not pursue the sport. On the other hand you could buy a rod you just love and become a fly fishing fanatic. This goes for both expensive and inexpensive rods.
