lambda genomic cloning vectors

[Your Name]

I am about to begin consturction of a genomic library of Trametes 
versicolor (a fillamentous fungus).  The question I wish to pose 
concerns which lambda vector to use.  The options provided in the 
promega and stratagene catologs sound very nice in theory but I was 
wondering if anyone had any particularly good or bad experiences with 
these vectors.  I will post a summary of the advice I recieve.
Thank You
