You might want to consider having your existing module repaired. There is a company called "Module Masters" in Idaho that will repair your module for around $500 and send it back to you with a 5-year warranty. Whole process takes 2-3 weeks. If it doesnt have anything wrong with it, they will send it back and only charge shipping. The other advantage to having your existing module repaired is that you shouldnt have to have it re-programmed by the dealership after you re-install it. If you buy a used module, you will have to take it to the dealer after you re-install and that'll be another $100.
