For you just starting out i would recommend something very friendly to new vapers,With that said would you rather have a Ecig that looks like the Traditional Cigarette,or would you rather have something just slightly larger that would provide you with longer battery life,Also do you prefer a Automatic or manual Ecig meaning one has a button and one does not?
Right off i would Recommend liberty flights like has been mentioned,Click the 20% off in the top left corner and select Riva 510 then scroll down and get the Special Edition for $34.39 for a complete kit .With this kit i would also recommend picking up some 510 Cartomizers just to get your feet wet and ease of use

Also you have the E-power which does not use proprietary batteries,and provides a good vaping experience,With long lasting battery life .Again with this kit i would Recommend picking up some 510 Cartomizers
E-Power Replacable Battery kit!
Or if you are wanting more a traditional Cigg size Ecig then you have a few options
The kr808d1 is a very good kit that is small in size but still provides a good vape

Keeping with the More traditional Cigg style you have also the 510 kit,i belive the 510 has shorter battery life then the kr808d1 kits if i remember correctly dont hold me to that though
