One of the things I picked up from ST Microelectronics was the STM32 Discovery board
The STM32 Discovery board is a simple eval board for the STM32F100RB (datasheet) microcontroller. The STM32 family of microcontrollers has a ARM Cortex M3 as it core. The board normally retails at about USD10, making it a very cheap 32bit eval board.
I haven't had a chance to fire it up, but it should be to start it up to develop some simple application for it.
