Well I always used to recommend the 901 and then a few months ago changed my recommended device to a Dura/510 but having been using cartos for a couple of weeks now, I am convinced they are the way
I use the Iolite a lot but tend not to recommend it to new people. As an ecig I had been using the Silver Bullet and Janty Kissbox Classix mostly, dripping them. Its so nice not to have to keep puiiling the mouthpiece off to refill, and not having to have a tissue to hand to mop up stray liquid. Its just so easy, go on you can now all say 'YES WE KEEP TRYING TO TELL PEOPLE' lol
Thanks for the comments on my page rusty. I need to rewrite the ecig page and feature these suckers
