Sent my transponder in to mylaps for an rc4 upgrade. It's about $47 after the $12 shipping charge to get it back to me. They sent it back out the same day they received it (Wednesday) and it will be at my house on Monday. As soon as they shipped it out they emailed me the tracking number. They also require a signature for delivery so figure that in to your plans if you decide to upgrade
