If in good shape those prices seem fair. From what I can see of the first bow the wood looks great and the finish does too. Check for major splits/cracks. Vertical splits aren't so bad as long as they are hairline type. Horizontal cracks and major dings in the glass can mean it's not shootable. Limb tips need to be good. Sights or sight holes can sometimes detract from the value.
I'd buy'em if I thought they were shootable. If you didn't want them, you could fleabay them or post in the classifieds here with good description and pics and get your money back.
