I have 9 metolius master cams for sale. None have been fallen on, I am the original owner, have been used for less than a year on ~25 pitches. For reviews and performance info please refer to this website:

I would like to sell them as a set rather than separate, if you choose to buy them separate I will do so for $45/ cam. (in stead of the $40/cam if bought together). I also have super cams in the two largest sizes I am selling as well as a BD Camalot #5 and #6. Depending on how much you buy I will work out a different deal for you. Feel free to call me with any questions or offers.

I live in Salt Lake City so it would be preferred if I could meet in person rather than the shipping and billing hassle. Have a great day!
