Option #1

The Smart Stick (click to purchase)

Looks professional at a cost of $200
Downside: The weight at both ends is the same, which is not how a golf club feels.

This is why I used a larger laser at the bottom of the Training Aid I use. 

Option #2

Make your own "Home made" Laser:

1) 1/2 PVC (Cut to 2 feet long)
2) Thick Laser (See picture)
3) Thin Laser (See picture)
4) 1 1/4 Washing Machine Hose 
5) Electric tape (See picture)
6) Rubber bands (to hold lasers running)

The Washing Machine Hose is sold in a 2 foot long size at Home Depot for about $6, this is an effective way to attach the thicker laser to one end of the PVC tube. Cut the hose to 4 inches long, enough to insert it long enough on one side of the PVC tube and to insert the thick laser on the other side leaving the possibility to extract the battery to be recharged without having to remove the laser each time, the other laser fits inside the tube with just a couple of wraps of electric tape around it.

Option #3

If there are enough Revolution Golfers interested to purchase this training aid from me, I'll look into improving it some and produce it to order. To be shipped within the continental US (sorry for international golfers). You may know that this is not a $200 Smart Stick professional training aid. 
But I am sure this training aid will last if you take a good care of it and will help you with your game. I'll have to put time into this project and I think I would be able to start shipping units in about 3 weeks.

I would like to suggest a price of $50 + $15 S&H
