Stopped by my dealer yesterday and was surprised to see a 400cm on the shelf, just arrived a few days earlier. Im in the process of selling a 200t so i bought it, $900 with 20" lite bar, though bar was backordered so i just used a regular bar for cutting today. Cut pretty strong while still on first tank, no problem with some 16" oak, real nice saw and feels similar in weight to my old metal tag 044. Power to weight prob still not quite as good as 462 but a little cheaper and feels similar, can't tell if magnesium piston is any different than regular, sales gimmick or a real advantage?. Pretty sure displacement is same as old 038 super while the 462 is same as old 038 magnum.
