29USD per piece is not that bad, do you know anything about that seller, or was just a search result ?
In any case, many thanks, I'll try to read the original fw and if I succeed is the less hassle way, assuming that I don't get some defective of remarked fakes.

 Cheers,

Would it not be more reasonable to trace the PCB it's on?

Sorry Tim, I think I've hit a language barrier, do you care to explain what you wanted to say a bit more in detail ?

Trace the PCB's circuit, reverse-engineer and replicate it whole?  With substitutions for available parts of course.
