I think what all these kit people claim, is a bunch of lies. The procedures 
look WAY too easy to get that good of DNA Yields. DNA. The best method in my 
opinion is still the old-fashioned NaI/NaSO4. I tried Millipore's *columns*
and let me tell you that I would have gotten more DNA if I held the agarose 
gel between my thumb and my index finger and squeezed!!!!
