I emailed Kurt -- he says he just ordered them from the same place all the rest of the AL2000s came from. He didn't seem to know *why* exactly there were such major differences. Interesting thing: there are two versions of the AL 3100 Floyd as well. Both have the standard clunky LP neck heel, but one comes with 24 frets, one with 22. I have one of the latter, but I've seen the 24-fret versions (they just move the bridge/bridge pickup toward the neck pickup about 3/4" to maintain the scale, and then lengthen the neck).
