I started with Inferno a month ago and still using it. Considering getting the Kamry K100 but haven't done it yet.
I bought a bunch of sample packs from different places and I guess that's what I would recommend.
(keeping in mind taste is very subjective) my favorite Volcano juices so far are Mango and Pearadise. Pearidise is still my fav from any
juice I've tried.
From Mt Baker I really like the hot chocolate.
From black velvet the grape drink and blue slush puppy are really good.
From Pink spot I like the Pineapple upside down cake and Janes Wild Juices
Didn't like any I tried from fuzion vapor. (They do get a lot of love here, no reason not to give them a try, taste being subjective).
Starting with volcano juices I got spoiled by not needing to steep the juices. Be prepared to give the juices you try from just about anywhere else a week or two to steep, a lot of them will have a horrid perfumey taste until they steep for awhile.
Best of luck!
