I've amplified inverse PCR fragments from Drosophila and housefly genomic
DNA of the length you are interested in using straight Taq polymerase and
long extension times (up to 6 minutes). Although I managed on one occasion to
do it with a single pair of primers and around 40 cycles, I now routinely use
two pairs of nested primers.
