I shoot an Oneida Black Eagle II and it's great. It looks complicated but it's really not. Dependable, forgiving and performs great. I have an Oneida Aeroforce as a backup and it is just as good except that it weighs more. If you can pick one of these up I would reccommend it.
In terms of the draw weight, you dont need to have it turned up as high as you possibly can have it. Find a weight you can smoothly pull it straight back, rather than lifting up the bow and pulling as you bring the bow back down. When bow hunting, same as gun hunting, its best to keep movement to a minimum. Holding the bow on the target and pulling back reduces percieved movement considerably. Also consider that you may have to hold the bow at full draw for a few minutes if your prey has a branch or tree infront of its vitals. When drawing back, make sure the weight is light enough that you can draw it smoothly without any shaking, jerking or any of that. In addition to being more visible to animals these actions can cause the arrow to either jump off the rest or rattle against it, depending on the type of rest. When you have to struggle to pull the bow, youll have trouble aiming it.
That being said, you should also make sure that the draw weight is high enough that the bow performs well. One person that I always see at the range had his bow set to 25 lbs and I tried shooting it. It does not group well (12-24 inches at 20 yds), the arrows fly on a very significant arc and it was a very poor performer. He cranked it up to 40 lbs and there were noticable differences, smaller groups (8 inches ish at 20 yds) and the obvious changes in arrow flight. Even at this weight I wouldn't be too comfortable using it as a hunting bow (if you even can use it for hunting anything at this weight).
My bow is set at 50lbs. I have a single red dot scope on it, sighted in at 40 yds and it consistently groups within 5 inches. On a good day it will keep them around 2 or 3 inches. One of the key points with archery, as with all shooting, consistency is key. Use exactly the same arrows, same length, same fletchings, same weight points and they should fly the same as each other. Rest the string at the same place, grip it in the same place with the release. Consistency is key. The same guy mentioned above used to use a cats breakfast of arrows and would get frustrated by the fact that the 3 of one type that he would shoot would all be close, while the others would be all over the place.
Good luck in whatever you choose, just remeber to practice lots and to keep consistent.
