Having recently been hit with laser in my home area, it's time to protect myself. I've start tom compile a list of people from other forums on a group buy for the Lidatek LE-20 Laser Diffuser (www.lidatek.com). It's the best rated and most effective system available. Prices are $350 - $450 depending on the unit you pick, and the discount will range from 10% - 20% depending on the number of total units. Email me at zaphods4@yahoo.com if you might be interested. The buy hasn't begun yet, I'm trying to get an idea of how many people might be interested. So far, it's looking good.
