SUre, you can go with a budget set-up and catch fish. I started steelhead fishing 5 years ago. At that time i picked up a scientific anglers 6 wt kit for all of 60 bucks. I used this rod for one season and caught a bunch of fish on it. I still have it and use it on occasion but mostly lend out to first timers. Now I have added 4 other rods,6 reels and my last fly line cost's more than my first outfit for comparison. So i would say go out there, buy the outfit to get started and upgrade once you find you like it. Happy fishing.
PS, take your time casting, it doesn't have to be fast or powerful.
