Hi:  May I humbly suggest Stewart and Via (1993):  A rapid CTAB DNA isolation 
technique useful for RAPD fingerprinting and other PCR applications 
BioTechniques 14:748-751.  This will give you DNA good for PCR.  In addition, 
we have been using it for screening transgenic plants, both for PCR, and if 
you increase the amount of fresh starting tissue, the method yields DNA of 
sufficient quality and quantity for Southerns.  
Cheers,  Neal
