Tired of my replacing my Ego batts and have been interested in a tank system for some time (I'm currently a dripper), I think this is the answer. Jumping on the BB bandwagon now. Need to get prepared though and order some cartos and batteries/charger. I think I've got the batteries/charger situation under control but I'm a bit overwhelmed by the cartos. Questions are- Where is the best place to get cartos for this use? Can I get pre-punched/drilled at an affordable price and where? Should I buy a carto punch and punch my own?
