I'm looking into building my first regulated box mod. I've built two unregulated mods, but have given them to friend as I like using tanks as well as my attys. I'm looking at the okl, sx350, and dna 120 chipsets. Any thoughts and or advice will be appreciated. Also would like info on sourcing parts and other tricks. BTW I'm going to Alaska on Friday and will be gone for two months. I'm planning on doing this as soon as I get home.
