Look up Rad's thread "Annual which bow manufacturer is the best?". It pretty well covers the nicer bows out there.
I'd seriously look at Elites based on their warranty and service alone. They aren't the most technologically advanced or the fastest things out there but they'll ship you, next day, a loaner bow to use if yours goes down during a hunt. They're quiet, smooth, and carry a lifetime warranty regardless of when or where it was purchased or by whom. That's hard to beat.
