HCigar HB40 with the Evolv DNA40 chip. Does both kanthal and nickel coils/wire builds. I like it alot.
Used to have iPV miniv2 70w, decent mod with enough power and memory settings I actually like and hope others would incorporate.
Sigelei 50w V2 is another good little box mod.
HCigar is coming out with a 35w with a removable battery similar to the look of a VaporShark rDNA mod for less (I don't think it's out yet.)
There's VaporShark rDNA clones that go up to 50w but, without temp. control.
iStick 50w.
SMOK Xpro 50/65.
Just what I've seen this week as well as what's out already.
I've owned and use HB40, iPV v2, and VaporShark DNA40 (smaller form than rDNA and battery not removable).
