Just now I went to
  http://ned.ipac.caltech.edu/ui/?q=byparams
and queried for z less than zero.

As I read it on first glance, it indicates:
 -- SDSS   knows of  903 galaxies with z<0.
 -- 2dFGRS knows of 2603 non-stellar objects with z<0.

You can probably do better by querying the primary sources
directly:
  http://www.sdss.org/dr13/
  http://www.2dfgrs.net/

Note that neither of them covers the whole sky.  But perhaps
they provide enough of a "list" to get started with.

If you want some examples that are bright enough to be
observed with a backyard telescope, there's always this:
