There are so many great bows to choose from that your options are incredible! High performance, low poundage bows are not that difficult to find these days, so here are some things to consider first:
What bow grip feels the best to you? The grip is your connection to the bow, so it needs to be comfortable and promote accuracy.
What kind of hunting do you do? Treestands, ground blinds, spot and stalk?? This might help you to decide on what length bow you might like to have.
Have you considered used? The classified section has some super bows with immediate delivery and good prices.
I own several bows that perform wonderfully at less than 45#. To name a few, they are Morrison Cheyenne, Marriah Thermal, Black Widow, Zipper, Adcock TD Longbow, and Schafer Silvertip. This list is not exhaustive, but it might give you some ideas.
Good Luck!
