What is the best (most effective) method for transforming yeast with a PCR product for integration?

Lithium Acetate, Electrophorhesis, others?

I used lithium acetate with no particular problems.
I never tried electrophoresis with a PCR product, but with a plasmid it gave a higher transformation efficiency.
you can find protocols here or there and other places (just google for yeast protocols.

Thank-you for that information
