I see there are a lot of these threads so sorry for posting another one, but I am looking at the pinnacle pro, arizer solo, no2, and davinci. I want the one that is most portable, fitting it in my pocket is awesome, and the one that smells the least. My friend has an no2 and I have used it before and its pretty awesome, if i could get a smaller one of those I would. I feel like pnp is what I want. input? For suggestions, dont want to spend much more than about 180 on ebay. Yes i know fakes are common on ebay.
