Personally I think the higher pricing on some bows coincides with higher speeds. They know people will pay a higher price for the fastest bow. When I first started out, 300 fps was the benchmark. I guess I've got a slow one now!
Martin makes some real nice bows and their packages are great. I was about to buy one when I happened to win a Parker Wildfire last year. Quite frankly, I never would have thought to look at one since everyone is "buy Matthews, no buy Bowtech, no buy Hoyt". I was going to trade it in and upgrade but I liked it so much I ended up keeping it. It shoots as quiet as my buddy's Bowtech Constitution (which absolutely is a nice bow). As for accuracy, I've only had the chance to sight in up to 30yds but it's hitting quarters. I have rotator cuff problems but it has never affected me.
My point is not to say "buy Parker", but as BT said, "Go try 'em all."
