IMO, I would recommend starting out the way I did way back when.... Get a Lynch Box Call, a Slate Call with an extra waterproof striker, crow call and owl hooter. Then have a friend show you how to run the calls or watch some video (not available when I started).
You can run the box call in a plastic bag if it rains, and you can dry your slate call with a bic lighter in the field.
Once you decide you like the sport then branch out to air operated calls and custom friction calls. If you are like most of us you will eventually collect more calls than you can use, but that's part of the fun.
A lot of success in turkey hunting is woodsman ship which you learn by the seat of your pants in the field.
The biggest tip I can give you is don't fall in love with your calling. IMO for most situations, subtle calling is better.
