Buy used. I bought a cheap bow for my first, a little more expensive for the second and by the third and expensive bow knew what I wanted and why I wanted it.
What I didn't know I learned, like bows in a shop people try out for feel are just put together, not tuned properly so going by feel really doesn't work, you could be shooting a very good bow but because of the way it was put together it vibrates and is loud. If you know what you want and can take the bow and make it right buy it barring some defect, you'll have what feels best to you.
My brother and I shot the same bow, he took his in for work and I do my own. He recently passed and I inherited his bow, the 2 are night and day, mine is extremely smooth fast and quiet, his is fast but a bear to pull and loud on the shot, I'm working on it.
Just buy a cheap (under 100) bow and get to working with it and on it. Took my first deer with mine, still have it, an old old Hoyt I bought for 50 bucks.
