Ab Gorrill at Lambacres.ca provides all of ours.  Speedrite (stayfix) reels and 400m turbowire.  The strands are tinned copper and much more conductive than regular polywire.  We have one Gallagher reel and 5 speedrites.  The Speedrite stuff is 1/2 the cost and just as good as the Gallagher.

I can dig up his number here if you are interested.
