great collection! Are you getting the Half X with ruby lenses? I have the Half X with polarized black Iridium lenses and I love them. But I have to admit I would love them more with ruby lenses. Ironically I was checking out the same ones you saw on Ebay. lol. I got lucky when I got my Black Iridium Hal x because they are new and only paid $189. A great deal considering the lenses are polarized too. Anyway, if you like Ruby lenses I think you will enjoy having that Half X Ruby in your collection. By the way, I love your avatar. Cyclops rocks!
Very nice catch with these Half-X eh?! As far as the Ruby Half-X goes... still not decided. I'm on the lookout for the Echelon posted on the Buy/Sell Forum!
