My used module failed after a short time working so I'm apprehensive in buying used again. Spending $1800 for new or rebuilt is not the best economics either for coupes you can currently buy for $2500 to $6000.

Has any electronics guru tried to fix these? What's so unique about them besides the connectors? Why does rebuilt cost nearly as much as new?

BTW, let me know if you have a used module, I would still consider it given my choices...
