Just so others know, my upgrade magnet board on mine failed the other day. F7 fuse blew, replaced it, and watched new fuse get bright red and blow. Powered down machine, called Stern, Chaz, helped me go through a few things like uplugging the 12 point connector on magnet board, put new fuse in, power machine on, and the fuse was fine. He said its a bad board. Chas said get in touch with distributor, I did, and an hour later get notified a new board is on the way its on its way. I see Marco's is selling the same boards for $70. So if out of warranty, etc. atleast theres a place to buy them.
