I think I've seen the Yahoo group you mentioned, and as I recall, the
focus (at least at the time) was on ribbon mics, similar to the
Nady-branded copy of the AEA "easier to manufacture" version of the RCA
77.

While I'm well aware that this is not the first time this sort of thing
has been done, this particular group has only existed for a couple of
weeks. Yes, there was a prior group buy that was managed largely by the
same group of people, and yes, the focus of the prior group was ribbon
mics. In this new instance, the selection has grown somewhat, though
the source vendor is the same.
