Keeping the likes of Razer and OCZ on their respective toes, Microsoft today added to its gaming mouse lineup with the addition of the Sidewinder X3, an entry-level rodent that won't chew through your wallet. Sporting an ambidextrous design, Microsoft's latest Sidewinder looks to sway budget gamers with a respectable feature-set, including a 2,000 DPI laser with on-the-fly sensitivity switching.

"Our research shows that in-game comfort continues to be the main consideration for PC gamers," said Bill Jukes, product marketing manager for Microsoft Hardware. "We designed this mouse to be ambidextrous and small in size, providing comfort to a wider variety of people and making it ideal for gaming as well as everyday use."

The Sidewinder X3 also comes with five programmable buttons (eight buttons in all), a wide, detented scroll wheel, and wide-glide feet "for smooth handling and a light, balanced feel."

Microsoft says the Sidewinder X3 will ship in May for about $40.
