While we are all suggesting modules again, I thought I would throw in
my suggestion:

Since Dieter and gang have embraced the Buchla designs I suggest they
take a look at the Buchla 259 Complex Waveform Generator. If you
know what this is, good. If you don't, you should check it out. It
is one of the most amazing oscillators ever built! I would gladly
pay as much as I pay for an A155 for an impressive Buchla 259 clone.
