I ordered a mini yesterday (silver/purple or purple/silver, can't remember which is the box and which is the door), and have a few questions. I have never used a drip tip, any favorites? Preference between metal and other materials for drip tips? How about batteries, I didn't think to order any, can I get them at Radio Shack, or other brick and mortar stores locally? I see several people are using cartomizers, what is the advantage? Are drip tips necessary or can I use an empty cart instead and would it dull the flavor or change things in some way? Thanks for your advise! Jeni
