Like the title says...I'm looking for an RD for instant on K. The staties in PA are the only ones allowed to use radar and this is the band that they use. I was looking at a refub'd Escort 8500 or a new Whistler Pro 78SE. Which would be better for PA? Or are there any other recommendations for instant on K? I have read this whole forum for a few days now and am still unsure which one to get.
