The first thing you need to do is see if crossbows are allowed during the archery only season in the state you are hunting in. I knowfor a fact crossbows aren't allowed in the archery only season in Texas. Bows make it more challenging anyway so I would go with a bow. There are a lot of good bows out there but the ones I would recommend are in the $700 range. If you are on a budget, go to your local bow shop and shoot whatever they have in your price range and pick the bow that FEELS THE BEST TO YOU. I think Diamond and PSEhave some pretty nice bows in the $400 - $500 range. For your first bow, look for a good package deal with a sight, quiver, and rest(probably a whisker bisquit). It will be hard to get everything you need for this season for under $500. You are right, you need to make an educated decision soon because becoming a good shot doesn't happen over night. Congrats on your decision to pick up bowhunting and don't worry, if you put forth the effort, you'll be ready come October. I must warn you though, once you start bowhunting you wont want to gun hunt anymore!
