A lot of us spent outrageous amounts of money trying different things when we started (or even STILL 

 )  But you're on the right track, and eventually, some combination of hardware/juice will "click" for you and you can relax.  TBH, some of us don't have just one combination that "clicks".  I've wound up with a good bottom feeder, a mod I made from some Radioshack parts, a Screwdriver, an Ego (with and without tanks), and a Smokefree.  I switch around between 
all of them.  It's an adventure, albeit a tasty one
