I use to be sponsored by radiopost and got my radio for free and will never suggest it to anyone. I had numerous electric run aways. Don't know if they ever took care of that issue and dont care. That free radio paid for itself with the parts needed to repair basically the entire car. I've heard of a steering lock issue with the 4PL but I have yet to experience it myself. I paid $209 new for mine and receivers are only $50. The backlit display and feel of the trigger is what sold me. The MT4 was high on the list as well. They both have the same trigger feel and I didnt have to run fuel tubing on the trigger to take up the huge gap between my finger and the brakes.
