I'm getting totally freaked out over the upcoming FDA regs, whatever they may be. Right now I'm using a Halo G6 kit. If there was any one setup to get in case the worst happens, what would you guys recommend? I'm thinking of something that would not go sour sitting quietly away for a little while, and would be reliable and easily maintained. (I assume that they cannot regulate batteries also used for other things, for example). Budget is a consideration; I cannot afford a Provari, even if I knew how to use one. Thanks!
