Maybe I didn't say it clearly enough, but no, the key is to get it back 
to where it is now so that the design doesn't change.
They have lots of these, but will run out. I didn't get into all the 
details, but the company who has been making it has raised the price 
significantly, and they're looking for move it to the US.
I know of the people here and trying to help them out.
At this point, they found a company who specializes in this, and would 
get back all the manufacturing files (gerbers & BOM).
