welcome @Timfrathar good luck with vaping - check out the wiki and marketplace i'm sure you'll find something there, if you're not sure ask and someone will be able to help.
Welcome! The marketplace has indeed quite a lot of options to get started. I started with an evod starter kit which is cheap and has been proved to be a fantastic introduction to vaping.
Hiya and welcome don't expect to find an eliquid that will fully replicate your ciggies. Tobacco flavours are just that, unburnt tobacco! Having said that, there are some very nice ones out there. Personally my favourite tobacco juice in mom and pops (either 10fkrty or American blend) but I'm no expert on them being mostly a sweet and fruity vaper
You can get mom and pops from leisure liquids. As you are coming off Marlboros I'd say you will probably need quite a high strength juice too, just to help with the cravings at first.
Welcome timfratar NIce to see someone else just starting to vape (like me) I'm on my 3rd day and its getting very hard, whilst the flavour of vaping is great, it isn't satisying my urge to go outside in the rain
Since your stateside, check out this company http://www.halocigs.com/triton-tank-system.html this is the kit I got my father (whos in the states too) and he stopped smoking on the 19th hasnt had a cig yet!
