So the kanger subbox is the top your list?
Evic VTC Mini (if you can find the 75watt upgraded get it, the standard 60watt can be upgraded to the ver2.0 firmware, the 75watt already has the firmware upgrade, upgrade also adds Stainless Steel Wire TC compatability), then the Subbox Mini or Nano, followed by the Sig Mini 30watt, Coolfire IV, then the Pegasus in that order. I own the Evic VTC Mini, Subbox Mini, Sig Mini 30watts, the Coolfire I've never touched to date though I've never had a problem with Innokin Products, I've owned 4 SVD's, 3 MVP (1 of each version up to the MVP 20watt), 3 iTaste VV's, 2 iTaste CLK's, and many iTaste Leo's (before they discontinued them) everyone was solid and kept up with my chain vaping habits

, I've seen the Pegasus up close and tinkered with it, was a customer's, nice little think 40watt mod, nice clean, nice asthetics, solid metal in a gun metal finish.
I'd suggest looking up some pbusardo, GrimmGreen, SuckMyMod, DJLsb, and Vapin Fagan, as well as
@dbrandt01 on Youtube for reviews and such on any mod you are interested in, watch several highly suggested, more points of view and views on strengths, weaknesses, plus, faults and such, the better you are informed to make a good decision on what to buy.
