Thanks to all who gave advice on my quest. Maybe I'll go to the B & Ms in my area (I think there are two). It would really be helpful if I could actually SEE any of this stuff in person and get a feel for what's involved. I didn't understand that a carto needs a tank, for example...which makes me realize that I have no idea what is is. Since I only know one person who vapes, and he is at the same level as me, I'm on my own. I'll also take a look at the Aspire.
I've spent so much already that I will stay with the itaste for now and work with figuring the best toppers for it.
Best theing I've learned this week? Snapple Diet Iced Tea with Peach is great for Dead Tongue!
Penny, as Storm said, you can just use a simple karto set up. Tanking it provides you with a constants liquid intake system, but you can also use it alone, and just top it off as it begins to use up the vliquid. Carrying around several filled kartos with different flavors is a really small and easy way to change up your vape on demand. And the addition of a sample bottle of extra liquid if needed for topping off also takes up little space. I'm all about the real estate aspect of vaping as I carry a tiny purse.
I think your idea of hitting a B & M is wonderful, by the way. Let us know how that goes!
