Impact archery collector 3 pin, if you like the pins bright until last possible legal shooting light. I bought the $20 light, but I would sell it in a heartbeat, because I don't see a need for it. The brightest site I've seen yet. The fiber optics run through the pin, not on the outside of the pin. The housing ring is clear plastic, but the rest of the sight is machined aluminum. It's easy to adjust too.
