My point on the 20 watts was that if you don't need to go over that the dna 20 would be fine and no need to wait around for a 30. Beyond that, to answer your question with any kind of relevance, we kind of need to know what you're looking for in a mod. Does it need to be VV/VW? Tube, box, or doesn't matter? What kind of a budget are you working with? Any other special requirements? With that info we can make some good recommendations for you. Without it people either won't answer or will just recommend what they likewhich may not be at all useful to you
