Subtractive cDNA

[MARK PEGGIE]

Hi,  I wonder if someone could give me some advice.  I am about to make a 
subtractive cDNA library but am not sure of the best approach.  I was going to 
follow a biotin/streptavidin method but found the PCR-Select cDNA Subtraction 
kit from Clontech.  Has anyone tried this kit - what are the advantages and 
disadvantages.
I'm sorry if this has been covered already.

Cheers
