I haven't bought a bow in a long while, so don't have any first hand knowledge to share. BUT - I would probably go to the Cabela's catalogue and pick out one of their package deals that includes bow, sight and maybe some arrows. A mid-pricerelease if you want one and you have the basics.
You can spend hundreds (many) trying to get the best sights, rest, release, silencers, etc, etc - But you can get a good bow that will kill deer and elk for a whole lot less.
One other option that I have - and you may also - is to go to a local sporting goods store that takes bows in on trade for the guys who always want the latest and greatest. These places usually have some real good deals on used equipment - and they may also have a range where you can try a few out to see how they fit you before buying.
A lot of "used" bows haven't really been used very much.

That's my 2 cents worth - and what I'd do.
