I have no doubt that the authentics are better quality than the SXK clones. At least I HOPE so
For me personally, the killer is the denial of access to Escribe. if I could get an authentic for the same price as the clone, I'd still take the clone for that reason. In fact, I may be willing to pay a little more.
I understand that DNA boards are more accurate than other boards, even in wattage mode. However, they are not better enough in wattage mode to make them worth the extra money in my very humble opinion. Find a sweet spot in just about any passably decent midrange board and I doubt anybody could REALLY tell the difference. Evolv is about TC (and now replay) and Escribe, and was about TC even before Escribe.
If I ran BBV, which obviously will never happen
, my first order of business would be to provide USB access forthwith and watch sales skyrocket even more. Whatever anybody wants to think about SXK, they are making a mint off of BB clones. They are getting almost as hard to find as the authentics. Yes, price and the "good enough" quality factor are the main reason, but I know that having that USB port is a deal sweetener that very much helps some people make their buying decision. I've seen some of them say so.
