Van,
There has been several posts on this subject, but I'll give you my take. I bought the HD Radar Detector because it is made by Escort. I have owned several Escort RD for my other vehicles. They have saved me several tickets, and if it was just one, it would pay for itself based on ticket cost and insurance. I know there is some debate over whether Valentine or Escor is better. I just figured they are the best, and since HD has a mount and it is all set up for mounting on the bike, I wanted to make it as easy as possible. See my pic below. One note is that you will have to modify your dash pad in order to use the HD mount. The nice thing is that it is realatively inexpensive to have an upholstery shop modify the dash pad, ($80). Also, with the HD system, the RD has a quick disconnect so you don't have to leave it on your bike when you park it. Let me know if you have any other questions.
