I need a transponder and I've seen a few used ones on eBay and this board. Some are 3-5years old and still asking for $320-350. A new factory transponder runs $448. Is the cost savings worth the $100? Or is a
5 year old transponder on its final leg?
Anyone every taken a transponder apart? I see a few dead ones for sale. I have access to some pretty talented electrical engineers who might be able to replace the battery. Anyone ever tried fixing a broken one?
Thanks for the advice,
Mike
