I'm looking at page 220 of the 2008 WM Port Supply catalog, where a Rocna 25 sells for $897.99. (Which is soooooooo much less than $900.00, apparently.) But on the regular WM website, NOT port supply, the same Rocna 25 sells for $812.What's that about? And, more to the point, has anyone found a supplier of Rocna anchors that offers any sort of a rational price?
