I'm looking to buy a new RD and hoping to pay about $150 or less. I bought a cobra 969 for sale last week for only $75 but after reading what people had to say about cobra rd's in general I reterned it. I remembered seeing a Whstler XTR 695 sale priced for $100 but their was only one and it was gone by the time I got back. I found a used K40 windshield mount rd for $80, as well as the XTR 695 for about $150 on Amazon. I was also considering an escort but I keep reading reviews on shopping sites that claim they tend to have mechanical issues and constantly need to be serviced... So anyways... In your opinion whats the best, most reliable RD I can get for my price range?
