RE: Final bow decision
I think the Q2 was an excellent bow and think that $500 is a very good deal on a new one. You typically get all of the "bells and whistles" when you buy on the high end of the price scale though that isn't necessarily saying that you need them to take a deer.
On the other hand Huntersfriend does have a nice enterprise going and I have only heard good things about their service and equipment. Either route should provide a relatively satisfying experience though I always tend to lean towards the local dealer in such discussions.
