Help! Need vector w/out homol. to pBR322

[ljw at rpiv.mc.duke.edu]

Please help, we need to find a vector with little or 
no homology to pBR322.  We need something with less than, 
say, 50bp of good homology to pBR322.  Vectors based on
pACYC and pSC101 are out because of homology in the ori.
It would help if any vectors you recommend have their
entire sequence in Genbank.

Thanks
