I've got a Sig 100W and love it despite the pointy corners. The market prices are going to drop once eLeaf rolls out the 50w iStick. The next gen of high powered mods will have a lot more bells and whistles, including temp control if you want to use it. I'd expect Sigelei, Cloupor, and others to drop their prices about 25-30% or more based off of what I have seen when new tech hits the market. DNA20 devices were $200+ when they first came out, now you can get a 20 watt mod for $30. The craze of ultra high wattage mods is slowing down, let's get real here - How many people will buy a 260 watt wunder-box and actually use it above 50 watts? Not many, thats where China miscalculated. There is a glut of wunder-box's out there that will have their price drop like a stone in order to clear them out so the new gen of tech enabled boxes can be sold.
I don't need bluetooth connectivity or temp control on my mods. Being able to tailor your vape, coil ramp up heating, and other things would be nice. Joyetech has a good system with the evic supreme and the myvapors application. Too bad others aren't doing the same. I've got my 3 favorite ejuice profiles stored on my evic supreme, each with a different coil ramp up wattage and ramp down wattage at the end of the vape. It works surprisingly well to bring out flavors in ejiuce.
If you want a wunder-box with high wattage, wait a bit. You'll be able to get one on the cheap in the next couple months.
