AZsmokefree.com has the parts to the "safecig" model which is RN4081, but a zillion times cheaper; batteries are $9.99, chargers are $6, and empty cartos are $5.95 for five, or a starter kit which includes more than safecig's for $39. *That* is what they should be sold for! It's not a bad little automatic actually if you like
vaping hands-free, it's just that safecig is a ripoff rebrander selling them for wayyyyyyy more than they're worth. I bought one before I found ECF, actually- it was not bad (other than the price) but their cartomizer flavors are utter crap, and they lie through their teeth about being "equal to two packs of cigarettes"- try maybe equivalent to eight at the very, very most. If you really want that model, get the parts from AZsmokefree.com and fill the empty cartos yourself.
ETA: There are *tons* of good juice vendors- the best ones for the closest you can get for tobacco flavors are folks who extract the tobacco flavors themselves, like Want2Vape.com and I believe Alien Visions (avejuice.com). Correct that they are not like burning tobacco- the taste of a good tobacco juice is more like the smell of a fresh pack of cigarettes, not the taste of a burning one. Many of us end up
vaping other flavors more than tobacco ones- myself for example; I prefer more bakery like flavors like Mrs. T's or KickBassVapors.
