Most cost effective source for residential wire and conduit?

Fiber's cheap... I'd just run it house to house, or should I say what we did between us and #1 Son's house, 3000 feet through the woods. You'll need a glass splicer though for connections... or access to one. Son got this one for $250 off of Ebay, I think they originally retailed for MANY thousands.

Running the splicer in the woods off three booster packs for enough 120v off one packs inverter.
