It took me about 45 minutes to make that one, but that was working slower for the sake of pictures, and saying "here, take a picture of this" when I needed him to.

It usually takes me 20-25 minutes for something that size.

As for selling, I don't discuss that on the internet. Nothing personal, but with items like that you get into sort of a gray area with legality and things like that. However, if anyone wants to discuss any topics in private via PM or e-mail, I can oblige...

There are a lot of imports out there these days (some even made well) which sell for cheap. That could be where your roommate got his. They can be had cheaply. The problem is most of them aren't annealed, so they run the risk of breakage. But, bigger pieces are where the money is anyways. Not little things like I'm making in that demo.
