Orange Whip Traing aid
TheSandTrap.com Top Picks
I have one. I love it. It IS worth the $100 if you actually use it for training and not just a way to loosen up before a round. I would be surprised if anyone could create something on their own with stuff lying around the house. I have a the Speed Stik that Vijay endorsed for the longest time and the orange whip is hands down a better swing aid. It'll help everyone from a beginner to a scratch golfer.
