Anyone take adv of Brake Buddy old for new discount?

We've had an original BB for 10 years and love it. About 4 years ago the lighter plug failed. Called BB and they offered a new unit at a substantial discount. I went to radio shack and bought a new cord and installed it myself. Since then I've upgraded the end that connects to the brake pedal. The original had a pin that dropped in that I lost. The new one is a slick spring loaded catch. I hope when this one finally dies they have the same trade in deal.
