Most cost effective source for residential wire and conduit?

Pulled it through 3/4" poly pipe, along with a 14/2 direct burial low voltage cable just to make it "fun" in case we needed some DC power later on. I had the 7000' spool of it, so while we were pullin... lol Then a porcupine decided it wanted to chew on the plastic pipe, fiber and wire and his internet went down... so we had to run a ditch witch machine through the woods and bury it all.

6 "wire" fiber is only about 20cents a foot.

The nice part about fiber is when lightning strikes it can't jump onto the fiber line like it can on cooper wire, that blows out the computers and routers on the ends of the runs.
