Promoter - probe vector needed

Can anyone provide me with a small plasmid vector containing a
promoterless LacZ (galactosidase) gene and an upstream polylinker
(NGATCN site needed) for the isolation of bacterial promoter sequences? 
The pBgal-basic construct from Clontech would probably work but is
somewhat large (7.5kb).
