I just finished putting together the Gen 1 MES 40 yesterday. It wasn't too bad, although I did have a bit of a hard time getting the controller to sit right with the stabilizing screw and what not.
For those of you that have the full SS body, how hard is it to maintain? It seems to scratch/dent fairly easily. There's already a small scratch on the top of the smoker and the interior of the door has a little ding.
I do miss the body of the Gen 2 - the black seemed to hide things a lot better and didn't seem nearly as fragile.
