I have been looking into building a high power box mod. I have been trying to get my hands on a dna30 but that hasn't happened yet. So that got me thinking about the alternatives. Maybe even something more powerful. I don't know what I'm looking for but I know what I want. I want power. I don't know what my options are in the way of chips. I would like for it to possibly run subohm but thats not a deal breaker as long as the power can make it up there. I would like to also shoot for the area of 50 watts or so, maybe higher. I also dont care about bells and whistles. I appreciate any and all suggestions/links.
