Try to spend as much money as you can on a bow set up. What's wrong with quality? Once you get set up and shoot a few times, you won't need to practice any more until maybe a day or two before the season starts. There's little maintenance on bows and it's not worth the time double checking the bow and your release. Go out and buy what you think you need, and once you get it put safely away in the garage you can relax and watch some tv until hunting season. Once the season gets here, get your archery gear out and throw it in the back of the pickup. Everything should still work fine, and practice is for losers with lots of spare time on their hands. Drive around until you see a shooter from the truck and go ahead and get the bow out of the case. Your release should be somewhere in the back of the truck too, go ahead and grab that. Once you are set look around for the arrows. Take the field tips off and put on the sharp ones that are for hunting. Hurry now, the buck won't wait for ever. If you cut yourself don't worry, they aren't sharp and it won't bleed long. Shake it off and GO SHOOT THAT MONSTER YOU DREAMED ABOUT! If he ran too far away, try aiming into the sky above him and see if you can drop an arrow down between his shoulder blades. The range on a good bow is 150+ yards you just need a few shots to pinpoint the location.
Just kidding, do the opposite of what I said and you'll be fine.
