I have a project I'm playing with on my Pi and USB dongle and been looking at coax options. The Ecoflex 10 seems to be a good balance for my toying around with. I can't seem to find a supplier though in the United States. I found one called Universal Radio in Ohio for $1.19 per foot. The two N type connectors would run me $11.95 a pop as well. Anybody have any other ideas/sources in the US before I pull the trigger on this one?
