I just pulled the trigger on a Quad LI for my Silver 350Z. (Hear that Cliff? Just ordered this afternoon!) I don't want to do the install myself so I'm looking now for some good shops. The problem is that there are some great audio shops around, but not too many that seem to have much experience with laser jammers. The local Car Toys may be my best bet since they sell and install the Escort 9500ci and ZR4. I'm thinking that they skill from installing those systems would transfer to installing the LI as long as I keep a close eye on them.
