I checked prices on the spirals when at the local dealer this week. New cost:$63.84 each x 2 per row x 6 rows = $766.08. Then there is all the labor of driving out the pins and taking off the carrier bearings to put the spirals on! From my checking so far the premium of a stripe head over a block decal one in the same basic condition is in the $800-$1200 range, so it may be worth only looking for stripe heads!
