I noticed a BIG difference when we upgraded our BioRad (actually, the old
one died).  The main advantage seems to be that you gan increase the
capacitance to 1070 microfaradays instead of only 970.  This results in an
optomized 40% efficiency for COS, for example, compared to only a few
percent transfected at 970 (titrating in various voltages at eachsetting,
of course).
