3rd Vote. I highly recommend the Uniden 436/536 HP over any Whistler product. Please, realize, I used to be a strong advocate for GRE, which was purchased by Whistler. However, they have failed to step up to the plate regarding radio performance. I know, without a shadow of a doubt, there will be other listeners reporting the opposite; however, I would review the many threads that have been written about Whistler products. Then, you can judge for yourself. I have monitored the system you are wanting to hear with success. Good luck.
