Tubes are just sweet. I'm going to shamelessly plug my Tesla Punk 86 watt tube now. Of all the tubes I have tried (and I have tried a few) I like this one the best compared to my Procyon's. It's not heavy, it's cute, it is efficient with power conversion (oh how I like Tesla's boards) and you can put a rather large diameter atomizer on top, I have a 24 on there with room to spare.
Feels good in the hand!
