Drippers tend to have the least amount of learning and highest success rate, its actually pretty difficult to fail coiling and wicking on those.
Recoiling some of your old coil heads is possible, they aren't particularly hard to do but take a little more dexterity and tax old eyes without help of some magnification.
Kayfun style atomizers are usually middle of the road for learning but once you have the skill down its a snap.
Older tank style atomizers like the genesis is going to either thrill you with the challenges or frustrate the heck out of you, they seem so simple, they can be the most difficult to get right.
I'd say go with something along the lines of an Aspire Nautilus, simply because if you find you don't like recoiling and rewicking you can use the store purchased coils and be done with it. You aren't going to need to adjust your juice nicotine content drastically with this device.
Or go with a dripper and be ready to buy lower nicotine content juices, the dripper atty tends to consume more juice and produce much more vapor.
