plasmid based fusion protein vec for immunoscreen?

[Jeffrey Joseph Martino]

Hi,

Immunoscreening fusion-protein cDNA libraries.  A quick look at
the (catalog) literature, shows lambda gt11-type phage vectors
with a cloning site that produces a lac-fusion protein. Are there
similarly designed _plasmid_ vectors out there?  If so would there
be any reason not to use them instead of phage?  We would prefer
plasmids this time.  Any comments are welcome.
