I've been looking mostly at dabuddha, and am probably getting this, although i've been considering the possibility of getting a cheaper one? whats the most i'd have to spend on a vape for it to actually be worth getting if im considering pretty much completely switching to vapes? Also, i've heard about legal herbs and stuff that have efffects when vaped, are any of these actually worth doing? if so which ones are the best? also, will a dabuddha still have a warranty if bought from a vape seller on ebay?
