My old pvc pipe creance cracked in the cold last year and I was about to make another one when I noticed this gizmo on the Western Sporting web page:

Laziness and curiosity prevailed and a few days later I had it in hand. I was using it and determined that while $40 may SEEM like a lot for something you can do cheaper, it is really a convenient and useful device. It is smaller than the old PVC pipe full of rocks AND it is a lot faster to dispense the cord or reel it in without getting it tangled. All in all I am happy that I didn't bother to inhale any more PVC cement and went this route instead.
