non-specific primers for human genomic seq

[Stephen Baird]

I'm looking for ideas or references on non-specific primers to
amplify human genomic sequences. I'd like to amplify small pieces
(around 200-500bp) preferably without repetitive elements and
preferentially amplify human sequences over any contaminating
sequence from bacteria. When doing database searches with small
pieces of human genomic sequence like 100-150bp, more often than
not the top scores are all human sequences even if the scores are
very low. How small could a sequence be that would still find mostly
human sequence?  For the primer, should I just use the most common
codon sequences that are not as commonly used by E. coli?

Thanks for any ideas or references,
