I looked at the dayacom site and really liked the look of the steelman, but to my knowledge no vendors I'm aware of carry it. But I too would like to find out, I would like to make a few.
Just be aware, the one pictured on the site is probably either a one off demo or at best one of a very limited number. They will probably have to send the order out for production regardless how many are ordered, so the lead time will be substantial, unless somebody else somewhere already has them in hand. (so I've heard)
I would strongly recommend you search for some of the Dayacom threads.. There is a lot of good information in some of them from a few people who have done this before... I'm not telling you not to do this, but you might want to arm yourself with all the info.
