Last year you could snag a set of these for about $20. You didn't really have color options besides whatever came up for sale, but they were still much, much cheaper.
I got an entire like-new cf frame with a set of natural wood grips for $20 (great deal, not likely to be repeated). They are comfy, but I wouldn't be buying just the grips for $45 to $50. Not trying to be a wet blanket on the sale, just my opinion. That may be why most of them haven't sold yet.
