I use the same technique to isolate DNA from agarose and have had quite a
lot of success with it.  I routinely get yeilds of ~50%.  As far as I can
see, the only thing I am doing differently is freezing the gel slice for
30min at -80C.  I recover the DNA by spinning the slices at 4000rpm for
15min in a microfuge followed by EtOH ppt'n.
