Before you buy one try the Hoyt Rampage XT its priced right and shoots awesome. Most of the money difference between the low to high price is in the material used to build em.
Lower priced bows uasually get you a magnesium riser instead of machined aluminum and the higher priced gets you laminated limbs also the cams are typically different.
This doesnt mean the lower priced bows dont shoot good. I shot alot of inexpensive bows that shoot great. Most times they are just little louder and little more vibration but still very effective killin critters. Happy Huntin
