I would highly recommend an inexpensive one piece, such as the KR808D-1. Simple, easy to use, and has worked great to get me off analogs.
VaporJunction has a full 808 kit for $24.95. Add a passthrough for $9.95. The prefilled carts that come with the kit aren't great, but the rest of the gear is top notch. Can't beat the price.
Then I would pick up some prefilled carts from Cigeasy and maybe some juice. I really enjoy their 555, 'Marlboro - USA Mix', and 'Camel - Desert Ship'.
I started with Cigeasy's 24mg 'Marlboro - USA Mix' and 'Camel - Desert Ship' and was off the analogs instantly.
I moved on to a few Tasty Vapor flavors but recently started craving 'tobacco' flavors and now 555 (Cigeasy) and Frisco (Vaporstation's 555) are my regulars along with the Cigeasy Marlboro and Camel.
I smoked for 15 years, pack a day, and haven't craved an analog since I got my first 808.
My dad, who smoked close to 2 packs for almost 50 years, also has the VaporJunction 808 kit and has kicked the analogs as well.
