What Ron said.
this is the older model, like mine, with analog thermostat and timer. As far as I know the current incarnation of Seal no longer supports this machine. If any of the components should go bad, and they will eventually, you might have a real hard time replacing them.
For about the same amount of money you can get a brand new heat assisted roller press from Drytac (and probably other sources). With the new technologies in printing constantly changing, and more of them being thermally sensitive, I would probably look at the roller press before considering what may well be an irreparable, obsolete machine.
