Chip====Spruce used to have them. Or they are easy to make. Trick is the amount of weight on the end so the hose will move.
NOTE----Teflon doesnt work well, I'm sorry to say. Its stiffer a compared to 701 hose, so it does move as well, without an excessive amount of weight. Nope, I havent come up with a good, reliable, inexpensive, live swivel yet so teflon can be used. (That way you dont have to change hose due to liner deterioration.)
