RE: How much should I budget to get started.
Go to your local sporting goods store and purchase a basic setup that you feel comfortable with and can afford. I started with everything used and was unhappy until I got an experienced person to help me setup something that would work for me. Last year I purchased a new bow completely setup at Scheels w/arrows and a new quick release for $450.00. This setup is great for me and I have no intentions of trading it out. I too am left handed and it makes it harder to find, but in your large sporting goods stores, you shouldn't have a problem. Good luck and welcome!
