I'm interested in the "features" you don't want to give up. SciPy core
should have all features of numarray.
Also, scipy core, numarray, and Numeric can all live together. If you
are using sufficient versions of each, you can exchange data via the
The ONLY reason I started scipy core was to unify Numeric and numarray
users. My selling documentation, should not be construed as anything
else but trying to help people who can't find time to contribute in
other ways to contribute to that goal.
If I was "just trying to make money," I would be doing something far
different than this...

It's actually there in Numeric (since 23.7 I think).
and also in (new) scipy
In (new) scipy you can also create new arrays from buffers very easily.
