Electrocompetent cells

Can anyone give me a protocol for the preparation of electrocompetent coli
which will give efficiencies greater than 10exp8 transformants / microgramme? 
Whatever the protocol , we always seem to be limited to 10exp6-10exp7, even 
when strains such as DH5a or XL1 blue are used.
