You should try out a carto tank. You can get an AGR tank cheap, and always buy a nicer pyrex if you find you like it down the road. Then just use unflanged cartos. I use Boge LRs but there are a lot of other options out there.

As for a mod I own an Evic, knockoff mechs, and a Vamo. Right now I must admit the mechs are my favorite, but i change devices like bad habits, so if youre anything like me, just get whatever you think looks most awesome at the time =) I like to buy my mods from vaportekusa or fasttech for the low prices.
