lacZ reporters

[Scott Vande Pol]

We are sick of doing cats and do not have a luminomiter (for luciferase)
and so we are looking for a good set of mammalian lacZ (beta-galactosidase)
reporter plasmids: one with a minimal promoter and cloning sites for
inserting enhancer fragments, and one with no promoter, but with cloning
sites for inserting promoters.  A high-copy plasmid would be nice too...  
		  Thanks for any help !
