Not sure exactly when the axe will drop, but the regulations are due to start in May. I suspect that prices will start to increase as people realise that time is running out. A few RDA's or RTA's and some wire wont cost much. Once you get used to building your own
coils to get the vape you want, I doubt you would go back to buying ready made
coils. When building for a mech you need to do some homework on battery safety, ohms law and heat flux to get the best out of them. It's more effort to begin with and takes a little time to get to your own personal preference's. After the initial learning curve you are rewarded with a very reliable setup.
