From shopping around, I did notice that I like innokin's iTaste series, but I'm not sure which one I should buy, as a beginner to the boxes, to learn on. I like the MVP 3, of course, but I am not sure if this will be too advanced for me. I am open to buying an earlier version of the MVP series or even the MVP 20W. I have tried to google this, but the "technical" talk is really confusing and I can't discern what's best for me.
