Check out-> Simons, Houman & Kleckner. 1987. Improved single and multicopy 
lac-based cloning vectors for protein and operon fusions. Gene. 53:85-96.

Really good vectors and system to move promoter-reporter to single copy (in
the chromosome as a lambda lysogen).  This can get rid of nasty artifacts 
due to multi-copy effects.  The only limits are the choice of sites, BamHI,
SmaI (In some cases) & EcoRI. If your promoter is known, you can PCR the 
region of interest with appropriate ends, pop it in and off you go.
