I am going on 5 years with my Ilumina that started my all digital shop. Basically, anything you can do on any other toner machine can be done with the Ilumina... with the exception of heavy coverage (unless you're on a service contract). You start getting over 30% coverage and the toner alone will cost more than what you are selling the job for. After learning that the hard way, this is what I use my Ilumina for:
-Addressing envelopes as well as printing them.
-Addressing offset shells.
-Biz cards on ultra thick stock. Forget 14pt, I'm talking 24pt!
-Invitations with matching envelopes. Since there is no click charge, you can run Park Avenue panel cards 1up for a few pennies in color.
-And you can print any odd job that won't fit through your other machines. One time, I printed a few hundred prayer cards that were 3"x4".
I'm in Cecil County Maryland, about an hour from Philly. Please call me, I would love to tell you all the good and bad about the Ilumina. I also know an excellent supplier (he sells the machines as well, but I imagine you are already talking to a sales rep) for the Xante- George Richardson in Virginia
Xante Laser Printers - Xante Color Printers - The Richardson Company. Between him and I, we could probably build the machines. But seriously, he offers free tech support to people who buy supplies from him. I would have thrown mine out the window if it wasn't for him.
