I agree with a lot of what others have said above....BUT, that being said, I also believe absolute confidence in your equipment is paramount. Your mind is THE most valuable aspect of shooting a bow, it can also be your biggest enemy shooting a bow. So if there is even .00001% doubt in your set up, that WILL eventually get into your head and negatively affect your shooting. You can go to most good pro shops and find brand new flagship bows that are just old stock, or even set up, used flagship bows in excellent shape, for really pretty good deals. That is the route I would suggest, unless budget is really no concern...which is not the case for most of us. The materials, and parts, in a higher end bow, absolutely make a big difference. Also customer service of a 'main line' manufacturer is going to be there with no question....even if you buy used, you may still have to pay for some parts or service....but they are still having your back. A good dealer is also an important part if you don't have the equipment and knowledge to work on your own bows.
Also, hiring a professional coach, or finding a knowledgeable mentor who is willing to help you, and show you the right things to do, and what not to do...are very helpful aspects. Once you decide that you are in for the long game....try to save up and get yourself a bow press and learn your bow intimately(some take this to that weird, yucky level😃)....but those are all things to consider. And be patient, and try to do your builds the way you really want them....the first time, even if that takes a bit longer.
Your bow should absolutely get the job done, if it is tuned, fits you...and you are taught the correct form, and execution of the shot process....but equipment is really secondary to proper form, fit, and shot execution.....just some things to consider. Hopefully I did not overwhelm you. Also do not try to shoot a bow that is too hard for you to easily pull back. If you can not sit flat on your butt...a d draw the bow STRAIT back, relatively easily...it is too much. Pulling too much weight will also destroy your form, and maybe your body.....
