Want to buy Choke-0-matic (any condition)

So you spend a lot of time carefully removing ceiling tiles. You have the water bottles to spray for keeping down the dust. You never remove more than two tiles at once. In short, you're spending a lot of extra time just pulling wire. The instruction say to run CAT 5 for data cable. But then you find out that (althought it is clearly printed on the instructions you have that CAT 5 is what to use) the manufacturer says NO! We didn't mean that kind of wire. So now you get to do it all over again. Just how unreasonable is it to expect to have an accurate listing of the wire type? Perhaps a WWF type HUG followed by the forceful application of the Choke-0-matic would solve this problem. It would sure make me feel a lot better.
