Hi Tony,

> I am not finding info on who makes the Silo 3d or the price.

It's made by a company called Nevercenter, the product page for it is here: http://www.nevercenter.com/silo/


And like Burr says, there's a different sub-d modeler called Hexagon which is available for free at this moment, I think it's a special until the end of the month, so grab that from here: http://www.daz3d.com
