Just to state the obvious:
It's not the "coil" going bad - it's the wicking material (usually cotton) inside the coil assembly that has a much shorter usable life than the coil itself, which is why it is much more economical to use an RBA rather than disposable coils.
Personally, I would at least try an inexpensive RDA or RTA. If you don't want to deal with spools of wire, just buy some pre-rolled coils and a bag of organic cotton balls. There is a very short learning curve, and barring any physical disability or dexterity issues, any able person can do it with minimal practice. A lot of people claim they are not "handy" and give up without even trying. Learning a new skill can be fun. Of course I will concede that there may be safety concerns, and some folks just don't want to bother or don't want to invest the time, but they must then deal with the available alternatives and expense.
Using an RDA or RTA will allow you to get months from a single coil, just dry burn the coil and replace the cotton wick when your vapor diminishes or starts to taste funky or burnt. It's really very simple.
