Our local branch of Ideal Electrical sells it by the metre.
Or you can just ask your local WISP - they will have heaps in stock.
Same, except its very expensive way of doing it, I think its like $5-6 per metre ?
Flick me a PM and you can go and put it on my discount at your local Ideal Electrical.
We do this with the local electricians and tv antenna installers who are installing cable for us on new house builds.
I doubt they would charge you $7 a metre if you were just walking in as a cash sale customer.
