This is Vanessa, just went in to see dean at Comtek to pick up a coax cable for mike and didn't find him helpful at all, in my past dealing with dean I found him much more helpful, today he didn't even answere my questions to my full satisfaction! After my purchase I'm still not sure I even got what would best suit mikes jeep! FYI you don't get your members discount unless you buy a complete system, which has never been the case in prior purchase! But who knows maybe he was having a bad day, we are human and entitled that! Lol
