If you need a quick piece, or not very much, you can buy it at stores like Fleet Farm, too... usually in 4 foot segments, but I've seen it in 6' or 8' pieces. Maybe Home Depot or Menards...

If I remember right it was somewhere between $15-$25 per 8'

Fleet Farm has a good selection (they're only in the midwest) but the prices, imo, are a bit high.
