While I can certainly see your point, I don't think most novice members would try to tackle replacing an injector without seeing what's involved, including the need to code the ECU with the "new" injector's value using INPA. Besides, it's not just to save "a few bucks" but well over a thousand. That said, the injector tips are extremely delicate and have to be carefully protected. New ones come with a metal cap to both protect the tip and to keep the o-ring compressed. Even if the injector was good when it came out of the car, it wouldn't take much to damage it so I'd have to think twice before buying one from someone I don't know.

A skilled DIY enthusiast that can code their own it might make sense to try but I wouldn't promote the idea of selling used injectors to novice forum members so they can try a save a few bucks.
