Ask HN: Any low cost laser metal engraving machines out there?

I figured HN was the best group to ask about this sort of thing.

A google search for "laser engraving machines" is awash with B2B websites.

Are there any laser engravers (capable of engraving stainless steel) that are affordable ($5k max) for the typical hacker available yet?

I noticed kickstarter had a fulfilled laser engraving project here but I doubt the units are still available seeing as it ended over a year ago: http://www.kickstarter.com/projects/fsl/affordable-20x12-laser-cutter-engraver-assembled-i
