Not exactly a stampede of interested parties, huh!

I suspect the lack of interest is based on two things. 1) someone who isn't an expert in the field heading up the project and 2) committing to an unknown end result.

You'd probably do better if you pursued a "group buy" and contacted the original reproducer to make another limited run. Or even contact those guys first to see what they'd need as a commitment to do a re-run.
