I think one of the best beginner outfits is the boxed set from Scientific Angler Usually around 70 bucks. You get everything you need in a balanced outfit, all you need are flys and maybe tippit and a couple of spare tapered leaders. Besides being a 3M product, I think they are a far greater value than most outfits in that range or cheaper. I still use several that I've picked up from Wally World on clearance.
And the easiest place to learn your casting is knee deep in a lake casting for sunnies, away from anything that will grab your backcast. Flyfishing videos can be very helpful as well as books, with pictures, like "The Idiot's Guide to Flyfishing"
The learning curve seems daunting at first, but at some point it will click and you'll first comprehend, then progress, then become a slave to an addiction. Sort of like the rest of fishing
