Before I make the plunge into purchasing the LI dual heads, I am in need of some assistance. I currently live in PA (Lancaster) a non laser State and although most stereo places say they can install jammers, they have never done so. I would like to get imput from other members in NJ, PA, MD, DC area's that can recommend a store for the install? I travel for work, so traveling to a close by State is in my not too distant future. Also, if there is a member who would be willing to assist in the install, i would gladly pay ($), lunch and/or even provide adult beverages. Thanks.
