zr3 or blinder? Help a noob out!

[John Bronze]

Hi, new here and I've looking into jammers, I was looking into the m20, and zr3. I realize that this question comes up a lot, but I've been searching for two days on this site and it seems that people have mixed reviews over those two. I've seen some people say they are good, and some say they are a waste of money. Now I don't want to spent over 500 for a jammer, so the LPP and AL are out of the question I own a black 350z. What do you guys recommend for that car? and I live in southern California also. here's a pic of the car, not mine but the same as mine Thanks http://www.scionlife.com/gallery/personal/36599_2.jpg

You might want to get an AL or LPP for it's parking sensor features since jammers are illegal in Cali

And Blinder M20 might give you enough proitection but with the big heads its easily seen
