The cost of poor cabling 1/1000 of good cabling. Tested older CAT5 (poorly installed) cable and discovered 100,000 bit error rate per 1 million sent on cable that was 395' (over limit). Installed CAT7 Belden cable and BER went under 100 errors per 1 million sent. This translated into dramatic reduction in re-transmissions which resulted in access time to network in seconds versus 1-2 minutes.

This gentleman is correct. The BICSI limit for Cat5 is 295'. Any further from pc station to IC will cause dramatic increase in bit errors proportional to distance over the limit and the # of "simultaneous" commands sent to server through hub.

the poorest cable is the twisted pair cable among the cables because it is easy to install and design for a LAN network

Twisted pair is the poorest cable because it's easy to install and design for a LAN? Right. Lemme get that down in my notes here...

Your question isn't entirely clear... initially you may save money with low quality cable and installation, but it may cause problems down the road that end with the cable being replaced, as was the case above, and when that happens you may end up buying overly expensive cable to make up for your mistake. Use decent cable to start with and you will be able to count on it for a long lifetime. Of course, for a patch cables, the cost of cheap cable is a buck or two less, and if it starts acting badly check it with a different cable, a buck or two over many cables really will add up... so it might make sense
