The Pockex seems popular.
Cutting down on the smokes is different for everyone, take it easy - if you want to do it you will.
As for liquid; there's loads on offer. Just avoid the evil rip-off brands (either tobacco companies or vaping businessmen) who pretend what they sell is superior. The 'fake' top rated brands are often those which pay the most commission. These brands are often supported by equally fake review sites and vaping magazines who are also in it for the money. The only exception I make to this sweeping statement is Halo. They make good liquids, shame about the hardware, which is just rebranding for higher ticket price business.
The best thing is to ask, really.
