Another vote for American Blend!  Back when I was trying really cheap juices I tried a Liqua juice ($3 per 30 ml).  If you smoked cigs in the past you may have screwed up by taking a pull from the temporary ashtray instead of the beer.  Exactly that taste, couldn't throw it away fast enough to keep from gagging.  I developed a rule from that experience that if the vendor is making juice that cheap and affording better is not possible I just buy unflavored and do myself a favor.
