Hey guys how about this product from mono price?
250' Monoprice Cat5e 24AWG Stranded Pure Bare Copper Wire Ethernet Cable 2 for $35 + Free Shipping
Baring any critters in an attic, most Ethernet cables that fail are those that are loose in open areas, and constantly being moved around, wound and unwound for packing unpacking vs static and isolated via clips in the walls to a port. It's like bending a paper clip, if you don't touch it it should fine beyond the life of whatever is connected on either end. I've worked as a fiber/copper/Ethernet installer and our plenum cables have been in place upwards of 8-10 years. The open office place and workshop cables barely last 18 months, wall ports even fail first due to excessive abuse. Open air cables fail due to getting rolled up and kicked, folded etc. At that rate, any piece of copper that size will break. When ever we went through a building, from access to distribution panels, we just tied off a new cable to the old ones and pulled it through. We tested with cable testers before we left. We typically were only called back to replace patch panel to switches which we made for client as well but they moved around at will. What do think of the price/use/value of the link I posted below? It's solid, and fire rated for in wall. I would probably need to get 2 spools.
