you can get the loc-line in new zealand. go to www.somethingfishy.co.nz and in the search box, type "product". it'll bring up 1/2" loc-line, 3/4 loc-line, and SCWDs.
i contacted the owner of the site and they said they had some SCWDs. must contact them at some stage to let them know to fix the site... :-?
