Lightning Round OT: 3D Systems, Deer Consumer Products and More

3D Systems : This printer manufacturer has had some real momentum, Cramer said. Asked to compare it to Research in Motion , the "Mad Money" host said 3D Systems is the better buy.

Deer Consumer Products : Do not buy shares of this Chinese appliance company, Cramer said. He thinks the People's Republic is “an accounting morass” and would also sell social networking company Renren . Baidu and Sina are the only two Chinese companies Cramer likes right now.

Teradyne : Cut your position in half because this stock is too speculative right now, Cramer advised. He said OpenTable is the perfect example of why home gamers are supposed to scale out as the stock goes up. That way, you are playing with the house’s money.
