I've had great luck using the zymolyase method followed by Geneclean,
resuspending in a final volume of 12ul.  Then I transform 80ul coli with
2ul DNA; you might want to try varying the amounts between 1ul and 5ul. 
This is just using homemade bugs at around 10^6 to 10^7, not ultracomps --
and I always get around 50 colonies per plate.  The only problem with this
method is that it is not rapid.
