+1 to the SubBox Mini Kit. that and a GOOD 18650 Battery and quite good to go (external stand-alone Charger is recommended by most as well).
Granted it will run you about 30-40 more than your expectations but as said quite right above;
Better to spend more now and be satisfied and Good to Go for a long time than to waste $50 now only to be left lacking and wanting more a month or so down the line. When that happens (and It Will), you will end up spending the $75-$100 anyways and be out the original $50 for Stuff to just lay around cluttering up the Place.
Love my Kbox (for Yard Work & the like) and my SubBox (for when discreet Equipment is preferable such as at the Movies, Kid's School Events, Jury Duty, Church and such) mated to the STMs and very pleasing Vapor and easy to use. Quite satisfying and adequate even compared to Mechs & RDAs (forgive me fellow Mech Warriors for I do stray at times)
Like them so much,,,, lookie what just arrived today all the way from Hong Kong!
