Building cabinet frames question.

I'm getting ready to make the cabinet frames for my TD and was wondering what would be the best way to put them together. This will be my first attempt at making a nice set of cabinets, so I can use any pointers you can supply
I was thinking about using biscut joints, since I have a biscut jointer, but the recent thread about them has me thinking otherwise. I know several of you swear by the pocket screws, but I really don't want to buy a new jig if I don't have too. So that leaves me thinking about dowels. I think my son left a dowel jig around here somewhere, and in the thread about the biscut joints it was mentioned that they (dowels) are stronger.
My frames (and cabinets) will be made out of Birch, if that makes any difference.
