It may be retired, but Sparkfun still sells it[1].

If you're looking for other faster microcontrollers with Arduino toolchain support, there's a bunch of stuff out there. See the Wikipedia page on non-atmega Arduino-supported boards: [2].

Additionally, if you're willing to learn how to use the ARM CMSIS HAL and write raw C++, there's the STM32 series of microcontrollers. Those also support Mbed, if you want to learn that instead (it's much easier than using CMSIS with C++, it's basically the equivalent of arduino for many 32-bit ARM microcontrollers).
