Has anyone tried this place for flavorings? They seem to have a HUGE variety and most have no sugars and only a few ingredients. They're about $4.50 per ounce. I'd love to try some DIY juice but can't figure out what everyone thinks is best. I've read most about Loranns, but keep seeing people comment on aftertaste. After all the start-up costs I've just paid out, I hate the idea of spending buttloads more and not liking it.
