my advice is:
1. what is weight and how are you going to hunt, it may be an issue.
2. is FPS important to you? if it is, go faster.
3. let off? will you possibly be holding for a long time?
4. PRICE! if all of these things are about the same go for the less expensive (only if it feels good)
I've killed more game with my 1st bow ($50) than any other bow I've owned. But I'm not into the whole "more expensive-the better" mantality, and only give the "get what you pay for" thing only so much clout.
Good luck and good hunting.
