Wow... makes me glad Janty has exclusive sales in Korea... the eGo is amazing. The comment made earlier about quickly wanting to try blue foam mods, XL atties, etc is spot on... I've got a ton of kit now
Obviously I'd suggest the eGo next time you look to purchase, it's been great to me. I highly recommend getting the USB battery as well, for 30 USD it's well worth it. I'm going to pick up a spare cable (the one from my camera has the same jacks) so I can keep one at the house, one in the car (have the car adapter as well, they threw it in for free) and one at the office. The USB battery allows you to plug it in to your computer (or wall if you use the wall adapter, or car, etc) while vaping. Standard battery requires you to take off the battery and screw it into the charger.
A note on the atties, I burnt one out my first week. Found I was trying to chain vape it and never let it really cool down. Now, 3-4 good drags, let it cool down for a minute, couple more drags... haven't had any problems since. Since I love vaping so much I just carry two on my and alternate every few puffs. Check to see how many atties the starter kit comes with (mine came with a Janty, warranted, one and a Janty TAWA, no warranty, one), if you get 2 atties just grab a second cone and you have two PVs to use. You can use it without the cone as well, and I will take it off (or loosen) depending on the mood. Draw is lighter (easier to draw, little less vapor) without the cone on, but perfectly usable.
My battery, even the standard ones, have lasted me a day and a half... and I'm puffing constantly. With the USB battery it's almost always plugged in, but I'm good to go if I head to the pub after work. Of course, even that's not a problem as the pub owner is the guy that got me into vaping, so can just barrow a battery from him while he charges mine.
As for juice, I use FSUSA (FreedomSmokeUSA) right now, 80/20 mix with some 70/30 on the way (any day now...). Their customer service is great, flavor is good, liquid VERY clear. A convert uses VaporBomb, heard good things about them as well. I've also tried House of Vapor, I won't try them again... nasty juice.
Well.. guess I rambled enough... if you can't tell, I love vaping and love my eGo.
