The iStick30 and Nautilus tank that Falconeer suggested is a good choice. I, personally, am not a fan of the Naut but lots of folks love 'em. I use a rebuildable tank (RTA). The istick will give you variable wattage, longer battery life and the ability to move up to higher performing tanks. I think you'll be very happy with that setup.
On buying from a shop (yeah the prices will be higher, but...) offer help when you have a problem and can provide hands on training for getting started. Their is more to the transition from a plug-n-play cig-a-like to a mod. Having a helping hand available when you need one, priceless.
