I am taking a new job at the first of the year that uses Esprit,I have used Mastercam for the last 3 years.I was wanting to know if there are any demo versions out there so I could try and get a head start.Any help would be appreciated.

Ask your future employer if you can borrow a copy of his Esprit CD. It can be installed on your PC, and run without a "dongle". The only limitation is that you can't save files, and you can't produce code.
