@stereo5 - I've built a couple of power cords (using both the 7N P2030 and the 7N P2040III -with Oyaide connectors - and enjoy both.
To make sure you are getting them from Japan (vs. Chinese copy), you can go to the www.fromjapan.com.jp and do a search for Acrolink 7N. They have most all of the levels of Acrolink products. Pretty good pricing as well. I think ebay usually lists where the products come from too (ie. Japan vs. Hong Kong). In response to your direct question, I don't have any experience with the Acrolink interconnects, but I'm sure they compete well at their price points as a result of their extreme purity and extrusion process.
