Hey everyone, I need help chosing between radar detectors. I can get a 9500ix for 200 locally which I thought was a good deal. Then I realized it was stupid because I live in VA and I don't want to risk getting caught, I would be super paranoid. So then I was looking at the STI because I know that is undetectable. Is that 100% true? What is the difference between sti and stir +? What do you think is best for me? I am new to radar detectors.
