Best advice I can give you, John is to check out a hamfest. Not Wireman though. Used wire is good too. Test for continuity. LOL!
I picked up a NEW! 60' roll 450 ohm last may for less than $14 Then last October I found a roll of old or used wire that was in fine shape. Almost 250' for $15. In both of course, I saved on shipping charges even though I spent gas to get there but, it wasn't just about the wire, it was about all the sights (and smells) of the hamfest scene.
