Awesome find btw !!
The spt2 is nice because it weighs a lot less, no ground to mess with ... and can be done for cheap. At this point, I don't plug any grounded cords into my AC controllers, so there is no reason to deal with all the weight and bulk. Nothing, incl. C9(s) even requires enough watts to warrant the big gauge cables ... so I really am enjoying lightweight LE(s). I grab an LOR box and its double the weight, just because of the cords. The LE board doesn't even have a ground to connect to.
