I'm getting them with 3 other pair of glasses off of the auction place. I don't think the person knew what everything was, so I took a chance and asked if they would end the auction for 25 and they said yes. So for 30 bucks shipped I got 4 pairs of glasses. One is an M-frame and one is this Zero. It is all scratched up, but at least I have one of these for now.
Zero - lil' beat up
M-Frame - I have a nose piece for these.
