commercial cDNA libraries

[*]

Dear newsgroupies,
My boss wants to get some access to a wild-tupe yeast cDNA expression
library, and is prepared to pay for one.  Does anyone know of commercially
available libraries and who produces them, and if they are any good?  Any
information would be much appreciated.
Thanks in advance,
Colin MacDiarmid,
