As a new guy in the sport, here are my questions:

1. Compound or cross bow? (Is this a highly debated subject?)
2. What brands/model bows should I stay away from?
3. If I buy a used bow, say on e-bay, what should I look for?
4. What are the most challenging aspects of bow hunting?
5. What are the benefits (why do guys get addicted to it)?
6. Other tips?

I'm sorry if this is too many questions, and if they have already been covered in this area. I haven't really read any threads in the bow hunting section before. Thanks in advance for any feedback!
