Yeah, I'm surprised that no one has tried to make a (nice) toy grade working zat. Something made from injection molded plastic, basic paint job, and a motor inside; that should be something that could be done for relatively cheap so long as MGM doesn't charge a ridiculous amount for licensing right and thus be sold for a fairly low price point. If they could make it to where they could make money selling it for around $75 - $100 they could make money hand over fist because that would be right at the price point that most Stargate fans could either afford it or be willing to save a bit to get.
