Most of the bowyers that I have met...and I've met a couple of the top-shelf ones...are just good-ol' folks making enough money to cover their love and passion for archery.
Some bowyers come out with something new, it gets publicity on the internet, and folks go wild over it and start placing orders creating a year-long or more backlog for the bowyer. Then another bowyer comes up with something else new and everyone rushes over to their camp scrambling to place orders..creating a backlog there also.
Meanwhile, there's just some solid bowyers sitting in the background making a good product day after day and making a decent living (Bob Lee Archery comes to mind). Nothing groundbreaking, nothing extremely fancy....just a good product with good customer service along with good business sense.
