What's the difference between all the different models? I have a couple 510's and am new to e cigs. I'm open to try different hardware and am trying to learn a bit more before spending the money. I'm interested in the 801 & 901 since they seem to be common here. Ultimately I'm looking for something that will produce a lot of vapor and is still portable. If you have another model other than the mentioned feel free to chime in. The more info the better.
Thanks
