I use cylinders also... I kind of have problems when im doing SubD organic things cuz it creates that nasty ripple thing at the top of the cylinder... I would like to be a box modeler haha but i just dont have the patience (or skill) to pull it off... theres also the technique of starting with a polygon and extruding out and out and out and it just keeps adding to the face, and you just keep pulling the edges out and soon you have a rough face RubberKidney has a tut on that... ill get you the link
