What a bummer about the first one. That's a lot to spend on a dud!
I know there are some entry level machines available for under $400. The "Da Vinci XYZ" line has a few. But they probably don't generate the kind of detail you're looking for.
What other applications do you have in mind for it?
To start, I think I will print some colored switch cover plates.
Then, I am sure I will find other usage for the printer.
