When you arrive at a price... I'll take them if you'll part with them. 8)
PS... I've paid from $235 to $375 for brand new 601 sprockets and I've paid as much as $300 for lightly used 601 sprockets...so mileage varies. Recovering them is $190 or if you take them to Fall Line they'll charge you a couple of children each for a recovering.
Now folks can espouse on what they paid and prove me lucky or spot-on...not sure.
