quasar redshifts
The two possible explanations of the quasars given a few days ago
missed a third:  that the red shifts really are Doppler effect, but
this does not correlate with distance the way it does for galaxies.
In other words, you can eliminate the need for a non-Doppler redshift
mechanism if you can devise a way of accelerating starlike objects
to substantial fractions of c (interactions with the magnetic field
of an exploding galactic core?).  At one time this was a respectable
theory;  I don't know its current status.  One problem is that one
should then see some blueshifted objects as well, although one can
fend this off by claiming that we aren't looking at the right
wavelengths to see the major emissions of a massively blueshifted
object.  How this explanation stands in the presence of increasing
astronomy efforts in the UV and X-rays, I don't know.

Any attempt to avoid the "cosmological" explanation of quasars also
needs to bear in mind that things like the recent case of double
images of a quasar being formed by gravitational lens effects of
a distant galaxy DO put a lower bound on the distance of SOME quasars.
