The BB7 Ko was announced first. Xtrans scrambled to compete, and smartly priced theirs around the same within like 24hours.
The KO being $30USD, and Xtrans making theirs like $35-$40USD.
BB7 is said to have schematics for multiple, so hopefully Xtrans stick to the price point throughout.
They say he quit & stole, he says he wasn't paid properly so sold the plans to make that up. Somewhere in there is the truth. In the grand scheme of things, he sold the shematics for absolute peanuts.
