Default WTB: Polygonal mirror (for scanning)

Does anyone have a 6-sided polygon mirror from a laser printer or out of some sort of laser scanning application? I actually had one from an old laser printer but threw it away. The ones on ebay are way too expensive for the project I want to complete.
Thanks.
Matt

I'll probably need something with variable speed. It's going to be a hard drive laser oscilloscope.
I found this:
http://cgi.ebay.com/4-Polygonal-Mirr...QQcmdZViewItem

- It's kinda pricey, I just need one mirror, I can easily rig my own dc motor. The link that I put above may not work as it only has a 4mm mirror height, not allowing much for a laser beam.

What kinds of laser printers have that mirror in usable form? Because I might be able to snag some old Laserjets for cheap from my university.

I'm not exactly sure - It's hard to say as designs on laser printers vary so much. Also, the printer has to be ripped to bits just to extract one small component. I've been considering doing the same at my university. I'll wait it out and see what our systems administrator says.
Thanks,
Matt.
