I think it really depends on what types of flavors you like. I've been getting my liquids from vista vapors who are dirt cheap, like eight bucks for 30 ml. But I vape all menthol flavors, and to me, since menthol is such a strong and pronounced flavor, it's probably the easiest to get right. I've tried menthols from other more expensive companies and vista's have been just as good if not better, plus they have like eight different "basic" menthol flavors, which is like double what most other companies offer. If you like more complex/gourmet types flavors, then I could see how some of the more expensive, high companies would be better. I guess I'm just lucky that I'm into such a cheap, simple flavor.
