just out of curiosity, what sort of price were you looking for and how well do you think the glowforge worked ?
They look like a lot of money for what they are (laser power isn't great) - but the glowforge software looks pretty interesting in the adverts.

I don't see why you can't sell one on here. Not a 3d printer but laser engravers and cutters are sort of, related.

So stick it back up if you want to :-)
