Try BIO101's Mermaid kit.  You need about 5 ul of glass fog/ 1 ug
of DNA.  It is relativly easy to isolate a few ug from a gel
slice - would that be enough for you?  I have used this kit many
times for gel purification of small fragments of DNA (down to 102
bp) and get 50 - 80% yeilds.
I have no affiliations with BIO101 or any other company.
