If you are jumping into the market, consider a variety of brands as well as the updated version of your old one, especially if your game is in a rut. There is some great new game-improving technology out there.

Selecting the correct racquet for a player's personal ability is the first step toward a successful match. But picking a new racquet is tough.

The number of brands and racquet variables can be confusing. Head size, swing weight and beam width are just a few things to consider. It's really not a quick one-and-done decision for most. Like most things that take time, however, it's worth it.
Pay attention to the level or kind of player that the manufacturer says each racquet is designed for. This will help you to narrow the selection. A beginner should not even bother using Roger Federer's exact Wilson racquet for example(below). Look for a beginner version of it instead. Same goes for Andy Roddick's Babolat.

Some racket facts that may help you:
* A heavier frame generates more power
* A heavier frame has less vibration
* A heavier frame has a larger sweetspot
* A stiffer frame generates more power
* A stiffer frame has a larger sweetspot
* A stiffer frame transmits more of the shock load to the arm than a flexible frame
* A stiffer frame provides a more uniform ball response across the entire string plane
* A larger head generates more power
* A larger head is more resistant to twisting on off center hits
* A larger head has a larger sweetspot
* A longer frame generates more velocity and therefore more power
* The string bed in a longer frame generates more spin due to increased velocity
*Wider beam widths offer more power, while more narrow beam widths offer better control 
*For more precise control, use a smaller head size (95 sq. in or less) and a narrow beam width (20mm or below)
 *For maximum power, use a larger head size (110 sq. in or more), and a larger beam width (26mm or more)

The new range of Prince tennis rackets, the EX03 gets a good review as does the new Wilson BLX range of rackets.
