If I got it checked by someone I trusted and the price was low enough that I could replace the limbs, cams, string and cables I might if the cost was low enough that I could replace all that plus limb pockets and rockers and still. Pretty much it would have to be about the price of a riser for me to consider it. And it would have to be a bow I liked in the first place. throw Axels and spacers into the mix as well, have seen bent axels on dry fired bows.
In other words doubt I would buy one, and I inspect some from time to time for others. I have seen some not show a problem with the limbs until after 50 or more shots after a dryfire and a few that the limbs cracked so you could find it after just drawing it back after putting on new string and cable. Sometimes there is internal stress fractures with the limbs that cannot be seen or felt until they rear their ugly head.
