I noticed that when it comes to the dna 30 chip there seems to be a fair number of options other then the Hana and the Cloupor's (rDNA, protovape, Zen's etc). The only 50 watt mods I've seen are the Sieglei, Cloupor, and the IPV2. Are there any other higher quality 50 Watt boxes out there? I'd like one as a back up to my mechs for when I'm traveling, working, etc.
