Thx Roland.

I looked over the Billet Box site, studied how they're put together, and I do think I would like it a lot better than a REO; they say the REO hits like a dripper, which I really don't like at all, but I use a cartotank daily, so if I was going to spend serious money on a mod, I'm certain it would be this one.
I haven't read the whole original thread, obviously, since it just piqued my curiosity today to wonder about these, but is there any plan to ever have variable wattage? I suppose I could go back to using voltage, and since the carto's resistance would always be the same, no real reason to change it, once I found the voltage I liked (I use a 3 ohm carto at 10-11 watts, whatever voltage that would translate to). Just curious, really.
Maybe it's something to think of, plan for, long-range -- like maybe next summer when I hit 1 yr smoke free, or something. They're nice looking, and I like the compactness of having everything all in one like that.
