It doesn't take too much experience, just practice, a few tools, and a little bit of math (which can be taken care of by going to Steam Engine or an app like Vaper's Toolbox).
It can be a bit of a hassle at first (especially if you have something like the Z4 I mentioned, that I can't rebuild without 2 pairs of freaking pliers!) but when you get into the habit, changing out a wick can be done in less than a minute, and a full recoil in 5. There's a lot of trial and error, at first, but just until you find out what you like. Then you just do it that way all the time.
It's also way, way cheaper. :) You can get your starting tools and enough kanthal and cotton to keep yourself building for a year for less than the cost of 2 boxes of Atlantis 2 coil heads.
Edit: It's also worth mentioning that it's much easier to learn to get it right with something easy to build on, like a Velocity clone or a Sapor - something with a big build deck and post holes is less of a headache than something like the Kayfun that has to pin the leads down under the screw head. Learn the basics, then worry about the specific atty's quirks, IMO.
Grab the Vaper's Toolbox to do the quick math. These batteries have a 35amp pulse rate but they spec out to 20a continuous. Just PLEASE be aware of what you are pushing. If you keep your Ti builds between .2-.4 you are good man.
You guys never heard of Vapers Toolbox on android? Free offline steam-engine on your phone. I go by that if I'm not near my laptop instead of visiting the site. Link because reasons

Steam engine is great but if you want something easy on the go vaper's toolbox is great link
