Jag, when you got to Home Depot (or a similar store), don't buy the pre-cut, prepackaged wire in 50' or 100' packs. Be sure to get to the bulk area, where they have the wire rolled up on big honkin' wheels and they cut to the length you want. MUCH less expensive. The quote at around $.22/foot sounds about right. If you are in Canada, it will be a bit more expensive, but should not even be close to $1/foot.
