The last kit I bought about 7 years ago was Helicoil brand (which I think is American?) which was $90. I don't know what Napa is but any auto related stuff is much cheaper in the US than here in Australia. The kit I got is Recoil brand which is made by Alcoa here in Australia.
I order all my CT and outboard parts from the US because they are much cheaper even when postage is factored in.
