I have been using boiling method to miniprep DNA for sequencing and it has
been successful.  Prepare plasmid (I used pUC) with standard method. 
Phenol extraction is not necessary.  Denature DNA with NaOH following
the procedure  of using Sequenase (2.0).  In the case of not getting enough
DNA, simply use 3.0 ml (spin twice), rather than 1.5 ml of culture.  pBR322
will probably work the same way even though I didn't try it.

Good luck
