I love my setup with an small ego one battery and a nautilus mini metal latticed tank. It's slightly thicker but shorter than a pen, but doesnt look like a saber and fit neatly in a small woman's hand. People tell me it looks quite stylish, but it still has a lot more power and larger tank than normal pens. Its also versatile - as people above mentioned you might want to test out better gear later, and both these parts are flexible (ego-one can sub-ohm).
