To make a reprap today is probably around 1,500$. Once we achieve practical replication and can produce the majority of the parts ourselves, the price will probably go down to 400$. The biggest hurdle is labor, because building a reprap today requires skills in many fields, and what you don't know you do slow. An old thread on costs is at:

By the way, where in Vancouver do you live?
