In capability it appears to basically be a "flat eggbot" and an eggbot costs $200. I bought one on sale back in '11 and have been inking a new personalized christmas ornament with it every season since then (more or less).
As a tool, its hourly cost has gotten pretty low compared to other toys. If I could find a similar recreational activity for this device, I'm just saying past experience shows that something similar ends up as a reasonable financial deal.
