if you dont want to blow $550+ on a vape, but still want one capable of filling bags, look into the Extreme Q, the Herbalaire, or the vivape 2 as a home option. if bags arent a concern for you, I would look at any 7th floor product. For portable, i would steer away from Pax because of its inability to be used with water pipes (thats one of the main reasons my friend got rid of his). Instead, i would look at either the inhalater, which works amazing with water pieces, or the solo, which has a gong adapter making for easy use with water pipes. if you want mere clouds, the inhalater produces the thickest clouds of any portable I've seen, but if you want taste, go with the solo, which still can get impressive hits. with the solo, there is the issue of size, making it somewhat less portable, with the inhalater, you get the reliability issue, as many units have had to get recalled, however, it seems as though these issues have been resolved. You also have $250 for inhalater and $160 for solo + price of gong adapter ($15-$20?).
