Hello. This is my first post and I probably should have read more before posting but I've been searching the net for a couple of weeks and haven't found the answer to my question, so here goes. (if I'm in the wrong area, someone please redirect me).  I have been smoke free since 07-25-10 when my first battery got charged on my enjoys.  They are wonderful and any time I crave a smoke I just whip that little thing out (actually I carry it around all day & ape like crazy!). I keep getting holes in my pre-filled cartridges and feel like I'm spending more money on pre filled carts than I did on smokes.  Additionally, the battery life on these things is awful!  I have bought 3 or 4 starter packs and have to recharge the battery every hour or so.  I have been looking for a new longer lasting battery and have decided that the janty ego will be my new ecig of choice.  The problem is, I don't understand what I need to get in order to NOT get the pre filled cartridges. Does the ego starter pack come with pre filled only?  Will I need to order an additional atomizer and/or cartomizer?  If I get just the atomizer, do I have to order a cartridge too?  The njoys that I have been using say that the nicotine is 1.8. Does that equal 18 in the e juice?  Finally, I was smoking black & mild pipe tobacco cigars. Is there any flavor of juice out there equivalent to that?  Sorry for the long post
