Nitto.
Nitto 115 bars have the traditional Maes bend and are available in various widths. The Nitto technomic stems are available in a wide choice of heights and extensions.
Harris Cyclery carries a nice selection of handlebars, including Nitto.
Traditionally, the bar width has been rather narrow for aerodynamic reasons, but in the past few years it has become accepted practice to choose wider bars for better chest expansion while breathing. The bars should be about as wide as your shoulders for better breathing efficiency.
