Have you ever tried using  'NUCLEON' kits marketed by Scotlab.

The kit uses dumb-bell shaped tubes and a silica resin slurry to separate
the DNA containing phase from the organic rubbish phase. (You do have to
use Chloroform).

Some of my colleagues prefer this method, and say that it requires alot
less pippetting, gives good quality DNA and in higher yields, than by
Phenol/Chloroform. They have also been know to work when the phenol/
chloroform extraction method has failed.
