200 20V Plug Wires Advice Needed

[Brice Warnick]

Thanks much, Eric!
This is the route I will go. These are the same wires that
www.blauparts.com sells for $179.95.
Kingsborne wanted $195.03 with free shipping. 
I can get them at Blau for $164.99  plus shipping using Blau’s $15.00
coupon. 
The Kingsborne wires also have a lifetime guarantee.
I like the idea of using the OEM Beru connectors.
Why is American wire better than European?
