I hate to break the news to you, but there is no easy way to stay away from analogs with ecigs. You could, I suppose, buy cheap disposables from China in bulk and end up vaping something like burnt shoe leather (on a good day).
Another alternative is to buy heads in quantity from China (Fasttech) which end up costing you around a $1 each. I have been waiting about a month for an order from them, and it just left HK. Life has been very busy for me of late, and there was no time to sit down to rebuild them. I am especially interested in trying micro coils and cotton.
Vaping brings out the mad scientist in some of us, and we can let out our creative self by tinkering with everything from mods to vaporizers to DIY.
With the purchase of Blu by AJR, big tobacco will do everything in its power to regulate ecigs. It is a battle in which the ecig community will eventually be beaten down despite our best efforts. There is just too much money involved, and the ecig industry is just too fragmented to put up a united front.
The tinkerers will survive. There is even a new mod out there with a "flashlight" head, and there are 510 flashlight heads available now so the power end will stay open.
You can rebuild vaporizers with off the shelf items until the cows come home.
Juices can also be made with off the shelf items. Nicotine availability could become an issue, but there are work arounds that are not all that difficult technically.
For now, your best bet is just to buy heads in quantity if you don't want to go through the trouble of maintaining them.
