The important thing is get a bow that the draw length fits you correctly and you are not overbowed ( pulling to much poundage ) It should be comfortable for you to shoot with the max pounds you can handle. Your bow shop should be able to set you up correctly with proper arrows and such. I assume you have a short draw length so I would use cut on contact broadheads.
Mission Archery; Martin Cheeta; PSE and several more have good entry level bows that are reasonable. Check other forums also to get a idea of price on the classifieds.
Good luck and enjoy your new sport.
