Those are your two main choices. Look for a module repair place that will refund the charges if the repair doesn't work. If it works, it is cheaper and saves coding (time and money)

I paid about $100 for any Indy to code mine. Call around to find a shop that can do it. The ones that do it will know immediately what you are asking for.
