I am curious about getting into smoking my own fish. Outside of actually catching the fish, what is the best way to get into smoking my own fish?

I have a Sears LP gas BBQ, but I remember my brother using a Lil Chief smoker. Now, I don't want to spend a bundle on a smoker for my first foray, so keep it cheap.
