I only use RTA's now a days, my latest is the Smok big baby beast the tank sells with an RBA deck. Great flavor and vapor and it comes with Stainless Steel coils, remove the wick, burn the coils to clean then rewick and your ready to go again. This is a 25 mm tank which may be to big for your vaporizer but I'm mentioning this to tell you about the Stainless steel.
