Unfortunately, it seems everything is coming out of China
these days and finding a local manufacturer is very difficult. There are several still in existence - New England
Rope, and others but naturally their prices are going to be significantly higher than the Chinese stuff. So it is a cost effectiveness decision - changing the "lines" more frequently or spending more to have them last longer. Colored line is always sore point for me. It only takes a year for the sun to bleach out the color. My personal opinion is that for temporary use and non-critical applications (e.g. tying down awnings, etc. ) the cheap
Chinese stuff is fine.
The key to cost savings on quality line is buying
full spools usually 500 to 600 feet. Then the prices are a fraction of the "per foot" prices. But what are you going to do with all the extra line after taking off a hundred or two for your primary need?
