I think the mods will get you. Since I started last August, I have stuck with 2 ego batteries, Ego T system, got a good carto tank from IBtanked and occasionally pickup a little Stardust or Nano here and there, box of carts, etc. I've spent less that $400 total. At a pack a day, I'd have spent probably around $3000 or more ($10+/pack here in Chicago). I just have to resist the urge to move up to the big boy toys. Just placed my first order with fast tech and was tough to resist loading up with those prices.
