The Grand Sixties model does look nice and I think I've seen these awhile back but not recently, so maybe they are also in short supply these days? Wouldn't mind owning a pair of those. I do have a mint pair of the Revo 840/001 which I was lucky enough to pick up a few years back on Ebay, but they don't pop up too often for sure. A guy was selling one of his two pairs, and his Buy it Now price was too good to pass up. Incidentally, there is a thread in here about Revo 840/001 lookalikes which occasionally pop up on Amazon, if you want the look without the high price. But they do fit a bit smaller than the genuine article. I agree that the mirror cobalt blue lenses are one of the best looks ever in shades.
