e-commerce package for printers

[cajun]

A printer is asking me about an e-commerce site, and I'd like to get some feedback. For those of you who have set up an e-commerce store for a printer, would Zen Cart be your first recommendation?

A typical sale would involve a customer choosing paper size, coating, paper stock, folding options, etc, and uploading a PDF file. Or maybe ordering reprints of an existing job.

Bonus points, of course, if the e-commerce software can pre-flight the PDF files uploaded.

I'm much more interested in open source, but would consider commercial options.

I know that there are several printers in germany and holland that use zen cart for there e commerce needs.
