Schweizer, H.D. (1993)  Small broad-host range gentamycin resistance
gene cassettes for site-specific insertion and eletion mutagenesis. 
BioTechniques 15:  831-834.

I have used these cassettes and they work well.  These cassettes are
based on the aacC1 gene, which confers Gm-R but not Kan-R.  One of the
cassettes is a derivative of the omega Spec-R/Strep-R cassette, the
other is pretty much just the gene and a polylinker.  In my hands, the
latter can be used to generate polar and nonpolar insertions depending
upon the orientation of the cassette.
