People like me must have bought them up. Last set I ran across were going for $45.00 at the Westminster swap meet last year. I grabbed them very quickly, and they're now on my Mavic neutral support bike.
RSX's are probably the best buy out there. Half the price of Sora, and shift a lot better. That's why you have a hard time finding them.
