Welcome and Hi
First most - we could help you better with a little more info. What is your budget, what are your most desirable features (like variable voltage, long battery life, ohm meter, etc) And what size/shape are you comfortable with? (tube mods, small tube batteries, cig a likes, box mods)
And for
juice - you are best off to go through the general e liquid section in the forum and read user
reviews of flavors that appeal to you and then get small samplers from those vendors. Also - if you have a B&M (brick and mortar store) nearby you can go there and sample juices. Taste is very subjective and there are 6874638748 flavors - so it is a matter of what appeals to you.
