If you can still find this model for sale, buy it, still a great product for the price.
Even though the DFR7 is discontinued and a couple of years out of date, its tech is still completely current and very usable for the average (speedy) driver. I was surprised how much advanced warning its sensitivity gives me, while filtering out a lot of the clutter. Also being able to "mark" the known false alarm areas, via the GPS, is golden. Buying this from the US at $260 CDN delivered, saved me around $200, over what they were selling for in Canada. I've owned several brands of RD's, starting with an Escort model #1 in the late 70's, and for the budget minded, the DFR7 can't be beat.
